ULTRA PETROLEUM CORP.  
2013 Shareholder Letter

Dear Fellow Shareholders

2013 was a re-balancing year for Ultra Petroleum. We continued with the prudent, rational 
business decisions in response to the prolonged weakened natural gas price environment. 
Also, it was somewhat of a bottoming out, the cyclical low for Ultra Petroleum in production, 
revenue, adjusted net income, cash flow, EBITDA, and margins. 

Now that’s behind us and we are back to our profitable growth 
phase. We are looking forward to generating strong cash 
returns and significant cash flow growth in this coming year. 
We are proud to recognize some of the year’s highlights:

•  Increased proved reserves PV-10 value 83 percent to  

$4.1 billion and volumes 18 percent to 3.6 Tcfe;

•  Achieved a reserve replacement ratio of 307 percent with 

industry-low finding and development costs of $0.53 per Mcfe;

•  Executed a $376.2 million capital investment program 

(excluding Uinta acquisition);

•  Maintained low cost leadership – all-in costs of $2.86 per 

Mcfe and cash costs of $1.81 per Mcfe;

•  Generated 55 percent cash flow margin and 28 percent net 

income margin (adjusted);

•  Acquired high-returning, accretive oil properties in the Uinta 

Basin for $650.0 million, and;

•  Raised $450.0 million of new debt attractively priced at 5.75 

percent with “BB” rating.

Let’s look at the year in more detail. A key determinant of value 
for any exploration and production company is reserves. The 
PV-10 value of our 2013 proved reserves increased 83 percent 
year-over-year to $4.1 billion. On a volume basis, they increased 
18 percent to 3.6 trillion cubic feet equivalent (Tcfe). Excluding 
the Utah acquisition that occurred in late 2013, the company 
posted an organic reserve replacement ratio of 307 percent 
and an organic finding and development (F&D) cost of $0.53 
per thousand cubic feet equivalent (Mcfe). In addition, our 
proved undeveloped (PUD) reserves increased 44 percent to 
1.7 Tcfe due to improved natural gas prices in 2013 compared 
to the prior year and a modest capital investment increase in 
our five year development plan. The increased PUD reserves 
are driven by net additions from our large inventory of Pinedale 
locations. We have ramped up from two to four operated rigs  
in Pinedale and our year-end 2013 PUD pool reflects this focus 
on high returns. With the future capital for our PUD reserves 
at just under $1.8 billion, the all-in F&D costs of our PUD 
reserves is a compelling $1.03 per Mcfe. Our year-end 2013 
PUDs do not include any locations from our recently acquired 
Utah properties. We expect to add high-value PUDs from this 
asset in 2014. 

We performed two sensitivities on 2013’s proved reserves.  
The first sensitivity applies a higher, more reasonable  
mid-cycle natural gas price of $4.50 per thousand cubic  
feet (Mcf), as compared to the 2013 year-end SEC price of  
$3.51 per Mcf. The PV-10 increases 38 percent to $5.7 billion, 
without any additional PUD pool capital. Also, in addition to 
running the price sensitivity case at $4.50 per Mcf, we ran a 
second sensitivity that included the locations and reserves  
that could be booked as PUDS if we expanded our investment 
levels and relaxed the five-year limits currently imposed on 
our PUDs. This sensitivity shows that with increased capital 
and no five-year limit to the PUD schedule, proved reserves 
exceed 7.0 Tcfe and the PV-10 value doubles to $8.5 billion. 
With more than 3.0 Tcfe of additional economic probable 
reserves, the company’s 2P reserves exceed the  
10.0 Tcfe mark. 

We executed what we believe was a very conservative capital 
investment plan in continued response to lagging natural gas 
prices during 2013. We had an initial plan of $415.0 million and 
as we reaped the ongoing benefits of increased field efficiencies 
during the course of the year, we decreased our capital to 
$376.2 million, excluding our Uinta acquisition, while delivering  
production within our previously announced guidance. This is 
half of the $835.3 million we invested in 2012 which was again 
half the $1.5 billion we invested in 2011. This dramatic under 
investment in dry natural gas over the past couple of years  
is in direct response to weak natural gas fundamentals. Our 
2013 production was 232.1 billion cubic feet equivalent (Bcfe) 
as compared to a record 257.0 Bcfe in 2012. We believe under 
investment was the right decision to help balance domestic 
natural gas supply and demand. 

Financially, we reported $506.3 million of operating cash flow  
or $3.28 per diluted share, generating free cash of $130.1 million  
in comparison to capital investments, exclusive of the year-end 
acquisition. Our net income (adjusted) was $253.2 million or 
$1.64 per diluted share. Our realized gas price including hedges 
was $3.57 per Mcf. 

While we have little control over the prices for natural gas, we 
can apply discipline with respect to our costs. Our all-in costs 
were $2.86 per Mcfe, including all cash and non-cash costs,

which includes field and corporate level expenses. On a stand-alone basis, our cash costs were $1.81 per Mcfe. Our cash flow 
breakeven is $1.62 per Mcfe. We delivered a 55 percent cash flow margin and a 28 percent net income margin (adjusted). While 
these would be considered strong for most of our peers, they are some of the lowest in Ultra’s history. 

In mid-December we financed our $650.0 million Uinta acquisition through borrowings of $200.0 million under our bank facility, 
together with the issuance of a new $450.0 million offering of five year senior notes at our parent level. The new notes priced at  
5.75 percent and were rated a “BB” by Standard & Poor’s. The operative financial covenant for the company is now effectively the 
Interest Coverage Covenant of 2.25 times in the new senior notes. This enables us to significantly add financial capacity and provide 
a strong foundation in support of future growth.

Let’s review Ultra’s operational highlights for the year. In Wyoming, our production remained essentially flat throughout 2013  
demonstrating that we can maintain steady production of around 165 Bcfe by investing $250.0 million. Two of the most noteworthy 
events in the field was our ability to meaningfully decrease Pinedale well costs. We realized an additional savings of $900,000 per 
well during the year, for an average well cost of $3.8 million. Second, we continued to drill more wells to total depth in less than  
10 days. In 2013, we drilled 54 percent of the wells in less than 10 days as compared to 33 percent in 2012. Our record drill time,  
as measured by spud to total depth, stands at 7.4 days, which we believe to be very close to the technical limit for drilling wells  
in the Pinedale field. 

Now to our newly acquired operations in Utah, that our New Ventures team identified as a unique opportunity within the Uinta Basin. 
This high-returning, accretive oil property was purchased for $650.0 million in mid-December. Ultra has a 100 percent working 
interest of this self-funding property. Now, having closed the acquisition and taken over operations in mid-December, we are still 
very excited about the well performance and operational results already being achieved in this asset. We look forward to keeping 
our shareholders apprised of key developments in this play during the course of 2014. 

Shifting to our Pennsylvania operations, we continued to withdraw capital from our Marcellus program due to low regional pricing 
causing returns to deteriorate and not be competitive with our Pinedale asset. During the year, we worked through our wells waiting 
on completion backlog with both our partners, Anadarko and Shell. Our Marcellus production is beginning to decline which we 
believe is the right thing to do with the limited take-away capacity out of the region.

We are looking forward to 2014, as we return to profitable growth mode at Ultra. We plan to invest where our margins and returns are 
improving and want to continue generating free cash in our core positions; expanding our margins and increasing capital efficiency.  
As a result of our $560.0 million capital investment program, we expect our cash flow and EBITDA will grow 40 percent from 2013 
levels. With this, we are targeting production between 243 to 253 Bcfe. Our focused capital allocation program will enable us to 
achieve a tripling of our oil production and steady gas production with more money being put to work in Wyoming and Utah while 
withdrawing additional capital from Pennsylvania as we expect widening basis differentials in the Marcellus to plague the region 
for the next few years. 

Our extended plan for the next three years has us spending $1.8 billion while generating $3.0 billion in EBITDA, with oil production 
increasing over eight fold and gas production remaining fairly flat. The tumultuous times of decade-low natural gas prices in 2012 
are behind us, and 2013 was somewhat of a settling out year. We are emerging stronger and more focused on the key drivers of our 
business to generate profitable growth. 

In closing, what distinguishes Ultra the most is our people. Our dedicated workforce of 124 employees is committed to responsible 
and safe exploration and production practices, as well as compliance with our health, safety and environmental procedures.  
We have weathered the tough times together and look forward to delivering on what already looks to be a terrific year and  
remain committed to executing our plan for the long-term benefit of our shareholders.

Sincerely,

Michael D. Watford 
Chairman, President and Chief Executive Officer

Certain Definitions

Terms used to describe quantities of oil and natural gas and marketing

•

•

•

•

•

•

•

Bbl — One stock tank barrel, or 42 U.S. gallons liquid volume, of crude oil or other liquid
hydrocarbons.

Bcf — One billion cubic feet of natural gas.

Bcfe — One billion cubic feet of natural gas equivalent.

Tcfe — One trillion cubic feet of natural gas equivalent.

BOE — One barrel of oil equivalent, converting natural gas to oil at the ratio of 6 Mcf of natural gas to
1 Bbl of oil.

BTU — British Thermal Unit.

Condensate — An oil-like, liquid hydrocarbon which is produced in association with natural gas
production that condenses from natural gas as it is produced and delivered into a separator or similar
equipment prior to the delivery of such natural gas to the natural gas gathering pipeline system.

• MBbl — One thousand barrels of crude oil or other liquid hydrocarbons.

• Mcf — One thousand cubic feet of natural gas.

• Mcfe — One thousand cubic feet of natural gas equivalent, converting oil or condensate to natural gas
at the ratio of 1 Bbl of oil or condensate to 6 Mcf of natural gas. This conversion ratio, which is
typically used in the oil and gas industry, represents the approximate energy equivalent of a barrel of
oil or condensate to an Mcf of natural gas. The sales price of one barrel of oil or condensate has been
much higher than the sales price of six Mcf of natural gas over the last several years, so a six to one
conversion ratio does not represent the economic equivalency of six Mcf of natural gas to one barrel of
oil or condensate.

• MMBbl — One million barrels of crude oil or other liquid hydrocarbons.

• MMcf — One million cubic feet of natural gas.

• MBOE — One thousand BOE.

• MMBOE — One million BOE.

• MMBTU — One million British Thermal Units.

Terms used to describe the Company’s interests in wells and acreage

•

•

•

Gross oil and natural gas wells or acres — The Company’s gross wells or gross acres represent the
total number of wells or acres in which the Company owns a working interest.

Net oil and natural gas wells or acres — Determined by multiplying “gross” oil and natural gas wells
or acres by the working interest that the Company owns in such wells or acres represented by the
underlying properties.

Prospect — A location where hydrocarbons such as oil and gas are believed to be present in quantities
which are economically feasible to produce.

Terms used to assign a present value to the Company’s reserves

•

Standardized measure of discounted future net cash flows, after income taxes — The present value,
discounted at 10%, of the after tax future net cash flows attributable to estimated net proved reserves.
The Company calculates this amount by assuming that it will sell the oil and natural gas production

3

attributable to the proved reserves estimated in its independent engineer’s reserve report for the oil and
natural gas spot prices based on the average price during the 12-month period before the ending date of
the period covered by the report determined as an un-weighted, arithmetic average of the first-day-of-
the-month price for each month within such period, adjusted for quality and transportation. The
Company also assumes that the cost to produce the reserves will remain constant at the costs prevailing
on the date of the report. The assumed costs are subtracted from the assumed revenues resulting in a
stream of future net cash flows. Estimated future income taxes, using rates in effect on the date of the
report, are deducted from the net cash flow stream. The after-tax cash flows are discounted at 10% to
result in the standardized measure of the Company’s proved reserves.

•

Standardized measure of discounted future net cash flows before income taxes — The discounted
present value of proved reserves is identical to the standardized measure described above, except that
estimated future income taxes are not deducted in calculating future net cash flows. The Company
discloses the discounted present value without deducting estimated income taxes to provide what it
believes is a better basis for comparison of its reserves to the producers who may have different income
tax rates.

Terms used to classify the Company’s reserve quantities

The Securities and Exchange Commission (“SEC”) definition of proved oil and natural gas reserves, per

Regulation S-X, is as follows:

Economically producible — A resource that generates revenue that exceeds (or is reasonably expected

to exceed) costs of the operation.

Estimated ultimate recovery (“EUR”) — The sum of reserves remaining as of a given date and

cumulative production as of that date.

Proved oil and gas reserves — Proved oil and natural gas reserves are those quantities of oil and gas,
which, by analysis of available geoscience and engineering data, can be estimated with reasonable certainty
to be economically producible — from a given date forward from known reservoirs and under existing
economic conditions, operating methods, and government regulation — before the time at which contracts
providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless
of whether deterministic or probabilistic methods are used for the estimation.

The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain

that it will commence the project within a reasonable time.

The area of the reservoir considered as proved includes all of the following:

a. The area identified by drilling and limited fluid contacts, if any,

b. Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be
continuous with it and to contain economically producible oil or gas on the basis of available geoscience and
engineering data.

In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known
hydrocarbons as seen in a well penetration unless geoscience, engineering, or performance data and reliable
technology establish a lower contact with reasonable certainty.

Where direct observation from well penetrations has defined a highest known oil elevation and the potential
exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the
reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher
contact with reasonable certainty.

4

Reserves that can be produced economically through application of improved recovery techniques
(including, but not limited to, fluid injection) are included in the proved classification when both of the following
occur:

a. Successful testing by a pilot project in an area of the reservoir with properties no more favorable
than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous
reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering
analysis on which the project or program was based.

b. The project has been approved for development by all necessary parties and entities, including

governmental entities.

Existing economic conditions include prices and costs at which economic producibility from a reservoir is
to be determined. The price is the average price during the 12-month period before the ending date of the period
covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for
each month within such period, unless prices are defined by contractual arrangements, excluding escalations
based upon future conditions.

Proved developed oil and gas reserves — Proved oil and gas reserves that can be expected to be recovered:

a. Through existing wells with existing equipment and operating methods or in which the cost of the

required equipment is relatively minor compared with the cost of a new well.

b. Through installed extraction equipment and infrastructure operational at the time of the reserves

estimate if the extraction is by means not involving a well.

Proved undeveloped oil and gas reserves — Proved oil and gas reserves that are expected to be recovered
from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for
recompletion. Reserves on undrilled acreage shall be limited to those directly offsetting development spacing
areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that
establishes reasonable certainty of economic producibility at greater distances.

Undrilled locations can be classified as having undeveloped reserves only if a development plan has been
adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances justify
a longer time.

Under no circumstances are estimates for proved undeveloped reserves attributable to any acreage for which
an application of fluid injection or other improved recovery technique is contemplated, unless such techniques
have been proved effective by actual projects in the same reservoir or an analogous reservoir, or by other
evidence using reliable technology establishing reasonable certainty.

Reasonable certainty — If deterministic methods are used, a high degree of confidence that the quantities
will be recovered. If probabilistic methods are used, at least a 90 percent probability that the quantities actually
recovered will equal or exceed the estimate. A high degree of confidence exists if the quantity is much more
likely to be achieved than not, and, as changes due to increased availability of geoscience (geological,
geophysical, and geochemical), engineering, and economic data are made to estimated ultimate recovery (EUR)
with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease.

Reliable technology — A grouping of one or more technologies (including computational methods) that has
been field tested and demonstrated to provide reasonably certain results with consistency and repeatability in the
formation being evaluated or in an analogous formation.

Resources — Quantities of oil and gas estimated to exist in naturally occurring accumulations. A portion of
the resources may be estimated to be recoverable, and another portion may be considered to be unrecoverable.
Resources include both discovered and undiscovered accumulations.

5

Terms used to describe the legal ownership of the Company’s oil and natural gas properties

•

Revenue interest — The amount of the interest owned in the proceeds derived from a producing well
less all royalty interests.

• Working interest — A real property interest entitling the owner to receive a specified percentage of the
proceeds of the sale of oil and natural gas production or a percentage of the production, but requiring
the owner of the working interest to bear the cost to explore for, develop and produce such oil and
natural gas. A working interest owner who owns a portion of the working interest may participate
either as operator or by voting his percentage interest to approve or disapprove the appointment of an
operator and drilling and other major activities in connection with the development and operation of a
property.

Terms used to describe seismic operations

•

•

•

Seismic data — Oil and natural gas companies use seismic data as their principal source of information
to locate oil and natural gas deposits, both to aid in exploration for new deposits and to manage or
enhance production from known reservoirs. To gather seismic data, an energy source is used to send
sound waves into the subsurface strata. These waves are reflected back to the surface by underground
formations, where they are detected by geophones which digitize and record the reflected waves.
Computers are then used to process the raw data to develop an image of underground formations.

2-D seismic data — 2-D seismic survey data has been the standard acquisition technique used to image
geologic formations over a broad area. 2-D seismic data is collected by a single line of energy sources
which reflect seismic waves to a single line of geophones. When processed, 2-D seismic data produces
an image of a single vertical plane of sub-surface data.

3-D seismic data — 3-D seismic data is collected using a grid of energy sources, which are generally
spread over several miles. A 3-D survey produces a three dimensional image of the subsurface geology
by collecting seismic data along parallel lines and creating a cube of information that can be divided
into various planes,
thus improving visualization. Consequently, 3-D seismic data is generally
considered a more reliable indicator of potential oil and natural gas reservoirs in the area evaluated.

Other Terms

•

•

•

All-in costs — For any period, means the sum of lease operating expenses, liquids gathering system
operating lease expense,
transportation charges, depletion,
depreciation and amortization, interest expense and general and administrative expenses divided by

General

PART I

Ultra Petroleum Corp. (“Ultra” or the “Company”) is an independent oil and gas company engaged in the
development, production, operation, exploration and acquisition of oil and natural gas properties. The Company
was incorporated on November 14, 1979, under the laws of the Province of British Columbia, Canada. Ultra
remains a Canadian company, but since March 2000, has operated under the laws of The Yukon Territory,
Canada pursuant to Section 190 of the Business Corporations Act (Yukon Territory). The Company’s operations
are primarily located in the Green River Basin of southwest Wyoming, the north-central Pennsylvania area of the
Appalachian Basin and the Uinta Basin in northeast Utah.

Oil and Gas Properties Overview

Ultra’s current operations in southwest Wyoming focus on developing its long-life natural gas reserves in a
tight gas sand trend located in the Green River Basin. The Company targets sands of the upper Cretaceous Lance
Pool
in the Pinedale and Jonah fields. The Lance Pool, as administered by the Wyoming Oil and Gas
Conservation Commission (“WOGCC”), includes sands of the Lance formation at depths between approximately
8,000 and 12,000 feet and the Mesaverde formation at depths between approximately 12,000 and 14,000 feet. As
of December 31, 2013, Ultra owned interests in approximately 84,000 gross (49,000 net) acres in Wyoming
covering approximately 190 square miles.

Ultra’s current operations in north-central Pennsylvania are focused on assessing, exploring and developing
its position in the Devonian aged Marcellus Shale and other horizons at depths between approximately 4,500 and
8,500 feet. At December 31, 2013, the Company owned interests in approximately 473,000 gross (250,000 net)
acres in Pennsylvania.

On December 12, 2013, the Company acquired oil-producing properties and undeveloped acreage covering
approximately 8,000 net acres in the Uinta Basin in Utah. The primary geologic target is the Green River
formation found between subsurface depths of approximately 4,000 and 7,500 feet. It is geologically similar to
the Company’s Pinedale asset in the Green River Basin, and the Company expects to apply drilling and
completion techniques similar to those it currently uses in the Pinedale field.

Business Strategy

Ultra’s mission is to profitably grow an upstream oil and gas company for the long-term benefit of its
shareholders. Ultra’s strategy to achieve this goal includes building a portfolio of high return investment
opportunities, maintaining a disciplined approach to capital investment, maximizing earnings and cash flows by
controlling costs and maintaining financial flexibility.

High Return Portfolio. Ultra seeks to maintain a portfolio of properties that provide long-term, profitable
lower-risk, repeatable, high return drilling

growth through development in areas that support sustainable,

7

projects. The Company continually evaluates opportunities for the acquisition, exploration and development of
additional oil and natural gas properties that afford risk-adjusted returns in excess of or equal to its current set of
investment alternatives.

Disciplined Capital Investment. Part of the Company’s business strategy includes proactive and regular
review of its portfolio of investment opportunities with a focus on investments that produce positive returns in
order to optimize return to its shareholders. Accordingly, in response to the low natural gas price environment in
2012 and 2013, the Company reduced capital expenditures by reducing the number of drilling rigs operating in
its Wyoming fields and encouraged the parties operating projects on its behalf in Pennsylvania to reduce their
activity as well. Reductions in the Company’s activity resulted in reduced capital spending during the current
year as compared to the prior year. The Company actively seeks to identify additional investment opportunities
that have the ability to profitably grow its business while diversifying its portfolio and leveraging its expertise in
unconventional reservoirs as a low cost operator. The Company actively works to identify appropriate entry
points into these opportunities through either grass root development or acquisitions. Accordingly, the Company
closed on the acquisition of crude oil assets in Three Rivers Field in the Uinta Basin in Utah. The acquisition
leverages the Company’s technical expertise as the Uinta Basin has similar tight-sand geologic characteristics to
the Pinedale Field, and the Company considers the returns associated with the Utah acquisition to be competitive
with its current investment portfolio.

Focus on Costs. Ultra strives to maintain one of the lowest cost structures in the industry in terms of both
adding and producing oil and natural gas reserves. The Company continues to focus on improving its drilling and
production results through the use of advanced technologies and detailed technical analysis of its properties. For
the year ended 2013, the Company’s all-in costs were $2.86 per Mcfe.

Financial Strength and Flexibility. Preserving financial flexibility and a strong balance sheet are also key
components of Ultra’s business philosophy. At December 31, 2013, the Company had cash on hand of $10.7
million and outstanding debt was $2.5 billion. At December 31, 2013, the Company had $540.0 million of
available borrowing capacity under its revolving credit facility. The Company’s average debt maturity is
approximately five years and the Company’s weighted average cost of debt is approximately 5.0%.

Exploration and Production

Green River Basin, Wyoming

During 2013, the Company participated in the drilling of 129 wells in Wyoming and continued to improve
its drilling and completion efficiency on its operated wells. During 2013, the Company’s operated wells averaged
10.3 days to drill a well, as measured by spud to total depth. This compares to an average of 11.5 days to drill
during 2012, a 10.4% reduction. Similarly, Ultra reached total depth in 10 days or less on 54% of all operated
wells drilled in 2013 as compared to 33% of operated wells in 2012. Total days per well, measured by rig-release
to rig-release, decreased 11% to 12.9 days in 2013 compared to 14.5 days during 2012.

During 2014, the Company plans to continue developing its position in the Pinedale field, and will continue
to target tight gas sands of the Lance Pool. All of the Company’s drilling activity is conducted utilizing its
extensive geological and geophysical data set. This data set is used to map potentially productive intervals, to
refine areas of drilling focus, to identify areas for future extension of the Lance fairway and to identify deeper
objectives that may warrant drilling.

Pennsylvania

Ultra continued exploration and development of its Pennsylvania acreage during 2013 participating in the
drilling of 20 horizontal wells targeting the Marcellus Shale. At the end of 2013, approximately 80% of the
Company’s acreage holdings in Pennsylvania was covered by high quality 3D seismic data, which the Company
uses to guide its investment decisions.

8

During 2014, the Company plans to continue its exploration and development efforts in Pennsylvania, but
anticipates a reduced level of drilling activity due to better returns realized in the remainder of the Company’s
current investment portfolio. The Company also plans to continue evaluating the potential for the Upper
Devonian Geneseo Shale Play across its Pennsylvania acreage position. Ultra’s current activities are located in
Potter, Tioga, Clinton, Centre and Lycoming counties and include lease acquisition, 3-D seismic, drilling,
completion, infrastructure construction and production operations.

Utah

On December 12, 2013, Ultra closed on the acquisition of approximately 8,000 net acres of oil and gas
properties in Utah’s Uinta Basin for approximately $649.8 million. Upon closing of the acquisition, the Company
immediately took over operations and maintained continuous drilling, completion and production operations. By
year end 2013, the Company drilled three wells in the field and plans to continue a one rig program throughout
2014. Ultra is the sole operator of the properties with a 100% working interest.

Marketing and Pricing

Overview

Ultra derives its revenues from the sale of its natural gas and associated condensate produced from wells
operated by the Company and others in the Green River Basin in southwest Wyoming, from the sale of natural
gas produced from wells operated by the Company and others in the Appalachian Basin in Pennsylvania and
from the sale of crude oil from wells operated by the Company in the Uinta Basin of Utah. During 2013, 97% of
the Company’s production and 88% of its revenues, after realized gains or losses on hedging transactions, were
attributable to natural gas, with the balance attributable to associated condensate and crude oil.

The Company’s revenues are determined by prevailing natural gas market prices in the Rocky Mountain
region of the United States, specifically, southwest Wyoming, and by natural gas market prices in the
Midwestern and Eastern regions of the United States. Additionally, with the acquisition of oil producing
properties in Utah, the Company’s oil revenues are determined by the price of domestic oil.

Natural Gas Marketing

Ultra currently sells all of its natural gas production to a diverse group of third-party, non-affiliated entities
in a portfolio of transactions of various durations and prices (daily, monthly and longer term). The Company’s
customer base includes a significant number of customers situated in the various regions of the United States.
The sale of the Company’s natural gas is “as produced”. As such, the Company does not maintain any significant
inventories or imbalances of natural gas.

Midstream services. For its natural gas production in Wyoming, the Company has entered into various
gathering and processing agreements with several midstream service providers that gather, compress and process
natural gas owned or controlled by the Company from its producing wells in the Pinedale Anticline and Jonah
fields. Under these agreements,
the midstream service providers have routinely expanded their facilities’
capacities in southwest Wyoming to accommodate growing volumes from wells in which the Company owns an
interest. The Company believes that the capacity of the midstream infrastructure related to its production will
continue to be adequate to allow it to sell essentially all of its available natural gas production.

In Pennsylvania, the Company and its partners are constructing gas gathering pipelines and facilities,
compression facilities and pipeline delivery stations to gather production from the Company’s newly completed
natural gas wells. Construction on these facilities continued throughout 2013, so the Company can manage its
midstream capacity to coincide with capacity requirements from its drilling activities. These facilities are
gathering systems and related infrastructure, and their construction is expected to continue, to some extent, until
the Company’s properties in Pennsylvania are fully developed. To date, none of the Company’s natural gas

9

production in Pennsylvania has required processing, treating or blending in order to remove natural gas liquids or
other impurities and it is anticipated that treating facilities of this type will not be required in the future to
accommodate the Company’s Pennsylvania production.

Basis differentials. The market price for natural gas is influenced by a number of regional and national
factors which are beyond the Company’s ability to control. These factors include, among others, weather, natural
gas supplies, imports from Canada, natural gas demand, inventory levels in natural gas storage fields, and natural
gas pipeline capacity to export gas from the basins where the Company’s production is located.

The Rocky Mountain region is a net exporter of natural gas because local natural gas production exceeds
local demand, especially during non-winter months. As a result, natural gas production in southwest Wyoming
has historically sold at a discount relative to other U.S. natural gas production sources or market areas. These
regional pricing differentials, or discounts, are typically referred to as “basis” or “basis differentials” and are
reflective, to some extent, of i.) the costs associated with transporting the Company’s gas to markets in other
regions or states, and ii.) the availability of pipeline capacity to move the Company’s gas to market.

Basis differentials in the Opal area have diminished to negligible levels when measured annually. This
meaningful decrease in basis is largely attributable to the increased availability of transportation capacity out of
the Rocky Mountain Region due to the addition of Ruby Pipeline and Rockies Express Pipeline. Over the past
year, premiums that have traditionally been associated with natural gas marketed in the Northeast have
disappeared as incremental supplies have been delivered to the market.

The Inside FERC First of Month Index for Northwest Pipeline — Rocky Mountains is the price that is
reflective of the Company’s gas sold in the Opal, Wyoming area and the Inside FERC First of Month Index for
Dominion Transmission Inc — Appalachia is the price that
is reflective of the Company’s gas sold in
Pennsylvania.

The table below provides a historical and future perspective on average annual basis differentials for
Wyoming natural gas (NW Rockies) and historically premium markets in the Northeast (Appalachia). The basis
differential is expressed as a percentage of the Henry Hub price as reported by Platt’s M2M (Mark to Market)
Report on December 31, 2013.

Oil Marketing

Wyoming. The Company markets its Wyoming condensate to various purchasers, which are primarily
refiners in the Salt Lake City, Utah area. The Company’s condensate realized pricing is typically based on New
York Mercantile Exchange crude futures daily settlement prices,
less a negotiated location/transportation
discount or differential. All of the Company’s condensate sales are denominated in U.S. dollars per barrel and are
paid for on a monthly basis. The Company routinely maintains only operating inventories of condensate
production and sells its product on an “as produced” basis. A portion of the Company’s condensate sales are
entered into by its operating partners in the Pinedale field.

At the end of 2013, more than 80% of the Company’s operated condensate production in Wyoming was
delivered directly into a pipeline, further reducing truck traffic and improving flow assurance as well as realized
pricing.

Utah. The recently acquired properties in the Uinta Basin produce what is typically referred to as Black
Wax Crude which is considered a medium grade of crude oil. This oil is marketed through long-term contracts

10

with refiners in the Salt Lake City, Utah area, aggregators and is also shipped out of the area via rail from various
rail loading facilities in the Salt Lake City region. The Company’s existing long-term transactions are expandable
to accommodate a growing production profile. The price for the Company’s crude oil production is typically
based off of NYMEX pricing for West Texas Intermediate Crude Oil and includes a basis differential or from a
posting for Black Wax Crude in the Uinta Basin.

Derivatives

The Company, from time to time and in the regular course of its business, hedges a portion of its natural gas
and crude oil production primarily through the use of financial swaps with creditworthy financial counterparties
(See Note 12), or through the use of fixed price, forward sales of physical product. The Company may elect to
hedge additional portions of its forecasted natural gas or crude oil production in the future, in much the same
manner as it has done previously. See Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

The Company’s hedging policy limits the amounts of resources hedged to not more than 50% of its forecast
production without Board approval. As of January 1, 2011 and 2012, the quantities that the Company hedged for
the succeeding twelve month periods represented 67% and 51%, respectively, of the Company’s forecasted
production for such periods. There were no open hedge positions at January 1, 2013. During 2011 and 2012,
Ultra’s board approved hedges of greater than 50% of the Company’s forecast production for each respective
period. (See Note 7 for additional information).

Significant Counterparties

A significant counterparty is defined as one that individually accounts for 10% or more of the Company’s
total revenues during the year. In 2013, the Company had no single counterparty that represented 10% or more of
the Company’s total revenues.

The Company maintains credit policies intended to mitigate the risk of uncollectible accounts receivable
related to the sale of natural gas and condensate as well as commodity derivatives. A more complete description
of the Company’s credit policies are described in Note 12. The Company did not have any outstanding,
uncollectible accounts for its natural gas and oil sales at December 31, 2013.

Environmental Matters

The U.S. Bureau of Land Management (“BLM”) initiates preparation of an Environmental Impact Statement
(“EIS”) relating to potential natural gas development on federal lands in the Pinedale Anticline area in the Green
River Basin of Wyoming. An EIS is required under the National Environmental Policy Act (“NEPA”) for major
federal actions significantly affecting the quality of the human environment and entails consideration of
environmental consequences of a proposed action and its alternatives. Although the Company co-owns leases on
state and privately owned lands in the vicinity of the Pinedale Anticline that do not fall under the federal
jurisdiction of the BLM and are not subject to the EIS requirement, the area north of the Jonah field, including
the Pinedale Anticline, which the EIS addresses, is where most of the Company’s exploration and development is
taking place. The BLM issues a Record of Decision (“ROD”) with respect to a final EIS, which allows for
surface disturbances for drilling and production activities within the area covered by the EIS, but does not
authorize the drilling of particular wells. Ultra, therefore, must submit applications to the BLM’s Pinedale field
manager for permits and other required authorizations, such as rights-of-way for each specific well or particular
pipeline location. In making its determination on whether to approve specific drilling or development activities,
the BLM applies the requirements of the ROD.

The ROD imposes limits on drilling and completion activity and proposes mitigation guidelines, standard
practices for industry activities and best management practices for sensitive areas. The Company cannot predict
if or how these adjustments may affect permitting, development and compliance under the ROD. The BLM’s
field manager may also impose additional limitations and mitigation measures as are deemed reasonably
necessary to mitigate the impact of drilling and production operations in the area.

11

To date, the Company has expended significant resources in order to satisfy applicable environmental laws
and regulations in the Pinedale Anticline area and other areas of operation under the jurisdiction of the BLM. The
Company’s future costs of complying with these regulations may continue to be significant. Further, any
additional
limitations and mitigation measures could further increase production costs, delay exploration,
development and production activities or curtail exploration, development and production activities altogether.

In August 1999, the BLM required an Environmental Assessment (“EA”) for the potential increased density
drilling in the Jonah field area. An EA is a more limited environmental study than that conducted under an EIS.
The EA was required to address the potential environmental impacts of developing the Jonah field on a well
density of two wells per 80-acre drilling and spacing unit as opposed to the one well per 80-acre drilling and
spacing unit as was approved in the initial Jonah field EIS approved in 1998. The new EA was completed in June
2000. With the approval of this EA and the earlier approval by the WOGCC for drilling of two wells per 80-acre
drilling and spacing unit, the Company was permitted to drill infill wells at this well density on the 2,160 gross
(1,322 net) acres then owned by the Company in the Jonah field. Subsequently, various other operators have
received approval for the drilling of increased density wells in pilot areas at well densities ranging from four
wells per 80-acre drilling and spacing unit to sixteen wells per 80-acre drilling and spacing unit. Current spacing
in the Jonah field is eight wells per 80-acre drilling and spacing unit (10-acre spacing) with several pilots testing
spacing at 16 wells per 80-acre drilling and spacing unit (5-acre spacing).

The BLM prepared a new EIS covering the Jonah field to assess the impact of increased density
development and define the parameters under which this increased density development will be allowed to
proceed. The draft EIS was made available in February 2005 and the final ROD was issued on March 14, 2006.
Key components of the ROD require an annual operations plan that includes all previous year activity including
the number of wells drilled, total new surface disturbance by well pads, roads, and pipelines, and current status of
all reclamation activity. Also required is a plan of development for the upcoming year reflecting the planned
number of wells to be drilled and an estimate of new surface disturbance and reclamation activity. Other
components include a drilling rig forecast, emission reduction report, annual water well monitoring reports, a
three-year operational forecast and the use of flareless-completion technology to reduce noise, visual impacts and
air emissions, including greenhouse gases as well as other monitoring and mitigation measures.

During the period from 2003 through year end 2011, Ultra and other operators in the Pinedale field received
approval from the WOGCC to drill increased density and pilot project wells in several areas in the Lance Pool
across the Pinedale field. During 2011, based on results of its 5-acre wells drilled in 2010, Ultra sought and
obtained approval from the WOGCC to file for development of its acreage in Pinedale at a well density of 32
wells per 160-acre government quarter section (5-acre equivalent).

Ultra, Shell and Questar (“Proponents”) submitted a development proposal for the Pinedale field, which
includes broad application of operations principles being evaluated in the demonstration project area. The
Proponents entered into a memorandum of understanding with the BLM to commence the preparation of a
supplemental EIS, or SEIS, for year-round access in the Pinedale field. The SEIS process included assessment of
alternative considerations and mitigation requirements that were considered as alternatives, or in addition, to
those included in the proposal. The proposal included commitments to reduce surface disturbance by utilizing
fewer overall pads and drilling more directional wells than called for in the 2000 Pinedale Anticline Project Area
(“PAPA”) ROD.

The final ROD (“2008 SEIS ROD”) was granted on September 9, 2008. The 2008 SEIS ROD allows,
among other things, for full field development from no more than 600 well pads field-wide, as well as year-round
development and delineation activity within big game (pronghorn and mule deer) and greater sage-grouse
seasonal use areas. Further, the Proponents agreed to implement numerous individual mitigation components.
These commitments include (i) the use of a full-field liquids gathering system, (ii) the use of advanced rig engine
emission reduction technology by at least 80% of the Company’s 2005 rig emission levels, (iii) a mitigation and

12

monitoring fund to address mitigation efforts to minimize impacts from energy development, and (iv) additional
funding for ground water monitoring on the PAPA. Additionally, ten-year planning and annual meetings with
BLM and appropriate state agencies will allow for proper community planning.

Also as part of the 2008 SEIS ROD, Ultra has offered to suspend additional activity for at least five years
from the signing of the SEIS ROD on certain leases. After the five-year period, leases under federal suspension
and/or “no surface” occupancy will be considered for conversion to “available for development” when a
comparable acreage in the core area of the PAPA has been returned to a functioning habitat.

In July 2009, Ultra, along with Shell and Questar, were awarded the BLM’s 2009 Environmental Best

Management Practices Award for Responsible Stewardship of Air Resources in the PAPA.

Regulation

Oil and Gas Regulation

The availability of a ready market for oil and natural gas production depends upon numerous factors beyond
the Company’s control. These factors may include, among other things, federal, state and local regulation of oil
and natural gas production and transportation, including regulations governing environmental quality, pollution
control and limits on allowable rates of production by a well or proration unit, the amount of oil and natural gas
available for sale, the availability of adequate pipeline and other transportation and processing facilities, and the
marketing of competitive fuels.

Most states, and some counties and municipalities, in which the Company operates also regulate one or

more of the following:

•

•

•

•

•

•

The location of wells;

The method of drilling, completing and operating wells;

The surface use and restoration of properties upon which wells are drilled;

Produced water and waste disposal;

The plugging and abandoning of wells; and

Notice to surface owners and other third parties.

State and federal regulations are generally intended to prevent waste of oil and natural gas, protect rights to
produce oil and natural gas between owners in a common reservoir, control the amount of oil and natural gas
produced by assigning allowable rates of production and control contamination of the environment. Pipelines and
natural gas plants operated by other companies that provide midstream services to the Company are also subject
to the jurisdiction of various federal, state and local authorities, which can affect our operations. State laws also
regulate the size and shape of drilling and spacing units or proration units governing the pooling of oil and
natural gas properties.

States generally impose a production, ad valorem or severance tax with respect to the production and sale of
oil and gas within their jurisdiction. States do not generally regulate wellhead prices or engage in other, similar
direct economic regulation, but there can be no assurance they will not do so in the future.

The Company’s sales of natural gas are affected by the availability, terms and costs of transportation both in
the gathering systems that transport the natural gas from the wellhead to the interstate pipelines and in the
interstate pipelines themselves. The rates, terms and conditions applicable to the interstate transportation of
natural gas by pipelines are regulated by the Federal Energy Regulatory Commission (“FERC”) under the
Natural Gas Act, as well as under Section 311 of the Natural Gas Policy Act. Since 1985, the FERC has issued
and implemented regulations intended to increase competition within the natural gas industry by making natural
gas transportation more accessible to natural gas buyers and sellers on an open-access, non-discriminatory basis.

13

The Company’s sales of oil are also affected by the availability, terms and costs of transportation. The rates,
terms, and conditions applicable to the interstate transportation of oil by pipelines are regulated by the FERC
under the Interstate Commerce Act. The FERC has implemented a simplified and generally applicable
ratemaking methodology for interstate oil pipelines to fulfill the requirements of Title XVIII of the Energy Policy
Act of 1992 comprised of an indexing system to establish ceilings on interstate oil pipeline rates.

If the Company conducts operations on federal, tribal or state lands, such operations must comply with
numerous regulatory restrictions, including various operational requirements and restrictions, nondiscrimination
statutes and royalty and related valuation requirements. In addition, some operations must be conducted pursuant
to certain on-site security regulations, bonding requirements and applicable permits issued by the Bureau of Land
Management
(“BLM”), Bureau of Ocean Energy Management, Bureau of Safety and Environmental
Enforcement, Bureau of Indian Affairs, and tribal or other applicable federal, state and/or Indian Tribal agencies.

The Mineral Leasing Act of 1920 (“Mineral Act”) prohibits ownership of any direct or indirect interest in
federal onshore oil and gas leases by a foreign citizen or a foreign corporation except through stock ownership in
a corporation formed under the laws of the United States or of any U.S. State or territory, and only if the laws,
customs, or regulations of their country of origin or domicile do not deny similar or like privileges to citizens or
corporations of the United States. If these restrictions are violated, the oil and gas lease can be canceled in a
proceeding instituted by the United States Attorney General. The Company qualifies as a corporation formed
under the laws of the United States or of any U.S. State or territory. Although the regulations promulgated and
administered by the BLM pursuant to the Mineral Act provide for agency designations of non-reciprocal
countries, there are presently no such designations in effect. The Company owns interests in numerous federal
onshore oil and gas leases. It is possible that holders of the Company’s equity interests may be citizens of foreign
countries that are determined to be non-reciprocal countries under the Mineral Act. In such event, the federal
onshore oil and gas leases held by the Company could be subject to cancellation based on such determination.

Surface Damage Acts

Several states, including Wyoming, and some tribal nations have enacted surface damage statutes. These
laws are designed to compensate for damages caused by oil and gas development operations. Most surface
damage statutes contain entry and negotiation requirements to facilitate contact between the operator and surface
owners. Most also contain binding requirements for payments by the operator in connection with development
operations. Costs and delays associated with surface damage statutes could impair operational effectiveness and
increase development costs.

Environmental Regulations

General. The Company’s exploration, drilling and production activities from wells and oil and natural gas
facilities, including the operation and construction of pipelines, plants and other facilities for transporting,
processing, treating or storing oil, natural gas and other products are subject to stringent federal, state and local
laws and regulations relating to environmental quality, including those relating to oil spills and pollution control.
The EPA has identified environmental compliance by the energy extraction sector as one of its enforcement
initiatives for 2014-2016. Although such laws and regulations can increase the cost of planning, designing,
installing and operating such facilities, it is anticipated that, absent the occurrence of an extraordinary event,
compliance with them will not have a material effect upon the Company’s operations, capital expenditures,
earnings or competitive position.

Solid and Hazardous Waste. The Company has previously owned or leased and currently owns or leases,
numerous properties that have been used for the exploration and production of oil and natural gas for many years.
Although the Company utilized standard operating and disposal practices, hydrocarbons or other solid wastes
may have been disposed of or released on or under such properties or on or under locations where such wastes
have been taken for disposal. In addition, many of these properties are or have been operated by third parties over
whom the Company has no control, nor has ever had control as to such entities’ treatment of hydrocarbons or

14

other wastes or the manner in which such substances may have been disposed of or released. State and federal
laws applicable to oil and natural gas wastes and properties have gradually become stricter over time. Under
current and evolving law, it is possible the Company could be required to remediate property, including ground
water, impacted by operations of the Company or by such third party operators, or impacted by previously
disposed wastes including performing remedial plugging operations to prevent future, or mitigate existing
contamination.

Although oil and gas wastes generally are exempt from regulation as hazardous wastes (“Hazardous
Wastes”) under the federal Resource Conservation and Recovery Act (“RCRA”) and some comparable state
statutes, it is possible some wastes the Company generates presently or in the future may be subject to regulation
under RCRA and state analogs. The Environmental Protection Agency (“EPA”) and various state agencies have
limited the disposal options for certain wastes, including Hazardous Wastes and there is no guarantee that the
EPA or the states will not adopt more stringent requirements in the future. Furthermore, certain wastes generated
by the Company’s oil and natural gas operations that are currently exempt from designation as Hazardous Wastes
may in the future be designated as Hazardous Wastes under RCRA or other applicable statutes, and therefore be
subject to more rigorous and costly operating and disposal requirements.

Hydraulic Fracturing. Many of the Company’s exploration and production operations depend on the use
of hydraulic fracturing to enhance production from oil and gas wells. Congress has periodically considered
legislation to amend the federal Safe Drinking Water Act to remove the exemption from permitting and
regulation provided to injection for hydraulic fracturing (except where diesel is a component of the fracturing
fluid) and to require the disclosure and reporting of the chemicals used in hydraulic fracturing. This type of
federal legislation, if adopted, could lead to additional regulation and permitting requirements that could result in
operational delays making it more difficult
to perform hydraulic fracturing and increasing our costs of
compliance and operating costs.

In addition, the EPA has recently issued draft guidance regarding federal regulatory authority over hydraulic
fracturing using diesel under the Safe Drinking Water Act’s Underground Injection Control Program. Further, in
March 2010, the EPA announced that it would conduct a wide-ranging study on the effects of hydraulic
fracturing on drinking water resources. The EPA released a progress report in December 2012 and final results
are expected in 2014. This study and the EPA’s enforcement initiative for the energy extraction sector could
result in additional regulatory scrutiny that could make it difficult to perform hydraulic fracturing and increase
our costs of compliance and doing business.

In addition, some states have adopted, and other states are considering adopting, regulations that require
disclosure of the chemicals in the fluids used in hydraulic fracturing. Additionally, some states, localities and
local regulatory districts have adopted or have considered adopting regulations to limit, and in some case impose
a moratorium on hydraulic fracturing. Although none of the Company’s properties are in jurisdictions where the
limits have been imposed, it is possible the jurisdictions where the Company’s properties are located may adopt
such limits or other limits on hydraulic fracturing in the future. The BLM has proposed rules and regulations for
hydraulic fracturing activities on federal lands. The Company and others provided written comment to the
proposed rules. Further, the EPA has announced an initiative under The Toxics Substances Control Act to
develop regulations governing the disclosure and evaluation of hydraulic fracturing chemicals and is working on
regulations for wastewater generated by hydraulic fracturing.

Superfund. Under the federal Comprehensive Environmental Response, Compensation and Liability Act
is joint and several for costs of
(“CERCLA”), also known as the “Superfund” law,
investigation and remediation and for natural resource damages, without regard to fault or the legality of the
original conduct, on certain classes of persons with respect to the release into the environment of substances
designated under CERCLA as hazardous substances (“Hazardous Substances”). These classes of persons, or so-
called potentially responsible parties (“PRP”), include current and certain past owners and operators of a facility
where there has been a release or threat of release of a Hazardous Substance and persons who disposed of or

liability, generally,

15

arranged for the disposal of the Hazardous Substances found at such a facility. CERCLA also authorizes the EPA
and, in some cases, third parties to take actions in response to releases and threats of releases to protect the public
health or the environment and to seek to recover from the PRP the costs of such action. Although CERCLA
generally exempts “petroleum” from the definition of Hazardous Substance, in the course of its operations, the
Company has generated and will generate wastes that fall within CERCLA’s definition of Hazardous Substances.
The Company may also be an owner or operator of facilities on which Hazardous Substances have been released.
The Company may be responsible under CERCLA for all or part of the costs to clean up facilities at which such
substances have been released and for natural resource damages, as a past or present owner or operator or as an
arranger. Many states have comparable laws imposing liability on similar classes of persons for releases,
including for releases of materials that may not be included in CERCLA’s definition of Hazardous Substances.
To its knowledge, the Company has not been named a PRP under CERCLA (or any comparable state law) nor
have any prior owners or operators of its properties been named as PRPs related to their ownership or operation
of such property.

National Environmental Policy Act. The federal National Environmental Policy Act provides that, for
major federal actions significantly affecting the quality of the human environment, the federal agency taking such
action must prepare an environmental assessment or an environmental impact statement (EIS). In the EIS, the
agency is required to evaluate alternatives to the proposed action and the environmental impacts of the proposed
action and of such alternatives. Actions of the Company, such as drilling on federal lands, to the extent the
drilling requires federal approval, may trigger the requirements of the National Environmental Policy Act,
including the requirement that an EIS be prepared. The requirements of the National Environmental Policy Act
in increased costs, significant delays and the imposition of restrictions or obligations on the
may result
Company’s activities, including but not limited to the restricting or prohibiting of drilling.

Oil Pollution Act. The Oil Pollution Act of 1990 (“OPA”), which amends and augments oil spill
provisions of the Clean Water Act (“CWA”), imposes certain duties and liabilities on certain “responsible
parties” related to the prevention of oil spills and damages resulting from such spills in or threatening United
States waters or adjoining shorelines. A liable “responsible party” includes the owner or operator of a facility,
vessel or pipeline that is a source of an oil discharge or that poses the substantial threat of discharge or, in the
case of offshore facilities, the lessee or permittee of the area in which a discharging facility is located. OPA
assigns liability, which generally is joint and several, without regard to fault, to each liable party for oil removal
costs and for a variety of public and private damages. Although defenses and limitations exist to the liability
imposed by OPA, they are limited. In the event of an oil discharge or substantial threat of discharge, the
Company could be liable for costs and damages.

Air Emissions. The Company’s operations are subject to local, state and federal regulations for the control
of emissions from sources of air pollution. Federal and state laws generally require new and modified sources of
air pollutants to obtain permits prior to commencing construction, which may require, among other things,
stringent, technical controls. Other federal and state laws designed to control hazardous (toxic) air pollutants
might require installation of additional controls. Administrative agencies can bring actions for failure to comply
with air pollution regulations or permits and generally enforce compliance through administrative, civil or
criminal enforcement actions, which may result in fines, injunctive relief and imprisonment.

On April 17, 2012, the EPA issued final rules to subject oil and gas operations to regulation under the New
Source Performance Standards (“NSPS”) and National Emission Standards for Hazardous Air Pollutants
(“NESHAPS”) programs under the Clean Air Act (“CAA”), and to impose new and amended requirements under
both programs. The EPA rules include NSPS standards for completions of hydraulically fractured natural gas
wells. Before January 1, 2015, these standards require owners/operators of oil and gas wells to reduce emissions
of volatile organic compounds (“VOCs”) during completions by either flaring using a completion combustion
device or capturing any natural gas not delivered into gathering pipelines in a process commonly referred to as a
“green completion.” During 2013,
the Company conducted “green completions” on all of the wells it
hydraulically fractured. Beginning January 1, 2015, operators must capture the natural gas and make it available
for use or sale. In addition, the rules establish new requirements, effective in 2012, for emissions from

16

compressors, controllers, dehydrators, storage tanks, natural gas processing plants, and certain other equipment.
These rules may require changes to our operations, including possible installation of new equipment to control
emissions. We continuously evaluate the effect of new rules on our business.

Clean Water Act. The Clean Water Act (“CWA”) restricts the discharge of pollutants, including produced
waters and other oil and natural gas wastes, into waters of the United States, a term broadly defined to include,
among other things, certain wetlands. Under the Clean Water Act, permits must be obtained for the discharge of
pollutants into waters of the United States. The CWA provides for administrative, civil and criminal penalties for
unauthorized discharges, both routine and accidental, of pollutants and of oil and hazardous substances. It
imposes substantial potential liability for the costs of removal or remediation associated with discharges of oil or
hazardous substances. State laws governing discharges to water also provide varying civil, criminal and
administrative penalties and impose liabilities in the case of a discharge of petroleum or its derivatives, or other
hazardous substances, into state waters. In addition, the EPA has promulgated regulations that may require
permits to discharge storm water runoff, including discharges associated with construction activities. The CWA
also prohibits the discharge of fill materials to regulated waters including wetlands without a permit.

Endangered Species Act. The Endangered Species Act (“ESA”) was established to protect endangered and
threatened species. Pursuant to that act, if a species is listed as threatened or endangered, restrictions may be
imposed on activities adversely affecting that species’ habitat. Similar protections are offered to migratory birds
under the Migratory Bird Treaty Act. The Company conducts operations on federal and other oil and natural gas
leases that have species, such as raptors, that are listed and species, such as sage grouse, that could be listed as
threatened or endangered under the ESA. The U.S. Fish and Wildlife Service must also designate the species’
critical habitat and suitable habitat as part of the effort to ensure survival of the species. A critical habitat or
suitable habitat designation or the mere presence of threatened or endangered species could result in further
material restrictions to land use and may materially delay or prohibit land access for oil and natural gas
development. If the Company were to have a portion of its leases designated as critical or suitable habitat, it may
adversely impact the value of the affected leases.

Climate Change Legislation. More stringent laws and regulations relating to climate change and greenhouse
gases (“GHGs”), including methane and carbon dioxide, may be adopted and could cause the Company to incur
material expenses in complying with them. The EPA has adopted rules under the CAA for the permitting of GHG
emissions from stationary sources under the Prevention of Significant Deterioration and Title V permitting
programs. The EPA has adopted a multi-tiered approach to this permitting, with the largest sources being subjected
to the permitting requirements first. These permitting provisions, should they become applicable to our operations,
could require controls or other measures to reduce GHG emissions from new or modified sources, and the Company
could incur additional costs to satisfy those requirements. In November 2010, the EPA published a rule establishing
GHG reporting requirements for sources in the petroleum and natural gas industry, requiring those sources to
monitor, maintain records on, and annually report their GHG emissions, with the first annual report, for 2011, being
due in September 2012. Ultra submitted the first annual report and all future required annual reports to date.
Although the rule does not limit the amount of GHGs that can be emitted, it could require us to incur significant
costs to monitor, keep records of, and report GHG emissions associated with our operations.

In addition to possible federal regulation, a number of states,

individually and regionally, also are
considering or have implemented GHG regulatory programs. These or other potential federal and state initiatives
may result in so-called cap-and-trade programs, under which overall GHG emissions are limited and GHG
emissions are then allocated and sold, and possibly other regulatory requirements, that could result in the
Company incurring material expenses to comply, e.g., by being required to purchase or to surrender allowances
for GHGs resulting from its operations. These regulatory initiatives also could adversely affect the marketability
of the oil and natural gas the Company produces.

The Company believes that it is in substantial compliance with current applicable environmental laws and
regulations and that continued compliance with existing requirements will not have a material adverse impact on the
Company.

Item 1A. Risk Factors.

Our reserve estimates may turn out to be incorrect if the assumptions upon which these estimates are based
are inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions will
materially affect the quantities and present value of our reserves.

There are numerous uncertainties inherent in estimating quantities of proved reserves and projected future
rates of production and timing of development expenditures, including many factors beyond our control. The
reserve data and standardized measures set forth herein represent only estimates. Reserve engineering is a
subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an
exact way and the accuracy of any reserve estimate is a function of the quality of available data and of
engineering and geological interpretation and judgment. As a result, estimates of different engineers often vary.
In addition, drilling, testing and production data acquired subsequent to the date of an estimate may justify
revising such estimates. Accordingly, reserve estimates are often different from the quantities of oil and natural
gas that are ultimately recovered. Further, the estimated future net revenues from proved reserves and the present
value thereof are based upon certain assumptions, including geologic success, prices, future production levels
and costs that may not prove correct over time. Predictions of future production levels, prices and future
operating costs are subject to great uncertainty, and the meaningfulness of such estimates is highly dependent
upon the accuracy of the assumptions upon which they are based.

The present value of net proved reserves included in this report should not be considered as the market value
of the reserves attributable to our properties. In accordance with SEC requirements, we base the present value,
discounted at 10%, of the pre-tax future net cash flows attributable to our net proved reserves on the average oil
and natural gas prices during the 12-month period before the ending date of the period covered by this report
determined as an unweighted, arithmetic average of the first-day-of the-month price for each month within such
period, adjusted for quality and transportation. The costs to produce the reserves remain constant at the costs
prevailing on the date of the estimate. Actual current and future prices and costs may be materially higher or
lower. In addition, the 10% discount factor, which the SEC requires us to use in calculating our discounted future
net revenues for reporting purposes, may not be the most appropriate discount factor based on our cost of capital
from time to time and/or the risks associated with our business.

Competitive industry conditions may negatively affect our ability to conduct operations.

We compete with numerous other companies in virtually all facets of our business. Our competitors in
development, exploration, acquisitions and production include major integrated oil and natural gas companies as
well as numerous independents, including many that have significantly greater resources. Therefore, competitors
may be able to pay more for desirable leases and evaluate, bid for and purchase a greater number of properties or
prospects than our financial or personnel resources permit. We also compete for the materials, equipment and
services that are necessary for the exploration, development and operation of our properties. Our ability to
increase reserves in the future will be dependent on our ability to select and acquire suitable prospects for future
exploration and development.

Factors that affect our ability to compete in the marketplace include:

•

•

•

our access to the capital necessary to drill and complete wells and acquire properties;

our ability to acquire and analyze seismic, geological and other information relating to a property;

our ability to retain the personnel necessary to properly evaluate seismic and other information relating
to a property;

18

•

•

our ability to procure materials, equipment and services required to explore, develop and operate our
properties; and

our ability to access pipelines, and the locations of facilities used to produce and transport oil and
natural gas production.

Factors beyond our control affect our ability to effectively market production and may ultimately affect our
financial results.

The ability to market oil and natural gas depends on numerous factors beyond our control. These factors

include:

•

•

•

•

•

•

•

•

•

•

the extent of domestic production and imports of oil and natural gas;

the availability of pipeline, rail and refinery capacity, including facilities owned and operated by third
parties;

the availability of a market for our oil production;

the availability of satisfactory transportation arrangements for our oil production;

the proximity of natural gas production to natural gas pipelines;

the effects of inclement weather;

the demand for oil and natural gas by utilities and other end users;

the availability of alternative fuel sources;

state and federal regulations of oil and natural gas marketing and transportation; and

federal regulation of natural gas sold or transported in interstate commerce.

Because of these factors, we may be unable to market all of the oil and natural gas that we produce. In

addition, we may be unable to obtain favorable prices for the oil and natural gas we produce.

Any derivative transactions we enter into may limit our gains and expose us to other risks.

We enter into transactions with derivative instruments from time to time to manage our exposure to
commodity price risks. These transactions limit our potential gains if commodity prices rise above the levels
established by our derivative instruments. These transactions may also expose us to other risks of financial
losses, for example, if our production is less than we anticipated at the time we entered into a derivative
instrument or if a counterparty to our derivative instruments fails to perform the contracts.

The adoption of derivatives legislation and regulations related to derivative contracts could have an adverse
impact on our ability to hedge risks associated with our business.

Title VII of the Dodd–Frank Wall Street Reform and Consumer Protection Act (the “Act”) establishes
federal oversight and regulation of over-the-counter derivatives and requires the Commodity Futures Trading
Commission (the “CFTC”) and the SEC to enact further regulations affecting derivative contracts, including the
derivative contracts we use to hedge our exposure to price volatility through the over-the-counter market.

In its rulemaking under the new legislation, the CFTC has issued a final rule on position limits for certain
futures and option contracts in the major energy markets and for swaps that are their economic equivalents (with
exemptions for certain bona fide hedging transactions); the CFTC’s final rule was set aside by the U.S. District
Court for the District of Columbia on September 28, 2012 and remanded to the CFTC to resolve ambiguity as to
whether statutory requirements for such limits to be determined necessary and appropriate were satisfied. The
CFTC appealed this ruling but subsequently withdrew its appeal. On November 5, 2013, the CFTC approved a

19

Notice of Proposed Rulemaking designed to implement new position limits regulation. The impact of such
regulations upon our business is not yet clear. Certain of our hedging and trading activities and those of our
counterparties may be subject to the position limits, which may reduce our ability to enter into hedging
transactions.

The Act provides a limited exception to end users (such as us) from the requirement to use cleared
exchanges, rather than hedging over-the-counter and authorizes the CFTC to set requirements to post margin in
connection with hedging activities. While it is not possible at this time to predict when the CFTC will finalize
certain other related rules and regulations, the Act and related regulations may require us to comply with margin
requirements and with certain clearing and trade-execution requirements in connection with our derivative
activities, although whether these requirements will apply to our business is uncertain at this time. If the
regulations ultimately adopted require that we post margin for our hedging activities or require our counterparties
to hold margin or maintain capital levels, the cost of which could be passed through to us, or impose other
requirements that are more burdensome than current regulations, hedging transactions in the future would
become more expensive than we experienced in the past.

A decrease in oil and natural gas prices may adversely affect our results of operations and financial
condition.

Energy commodity prices have been historically highly volatile, and such high levels of volatility are
expected to continue in the future. We cannot accurately predict the market prices that we will receive for the
sale of our natural gas, condensate, or oil production. Information about revenues attributable to our derivative
transactions is available in Item 7-A — “Quantitative and Qualitative Disclosures About Market Risk.”

Oil and natural gas prices are subject to a variety of additional factors beyond our control, which include,
but are not limited to: changes in the supply of and demand for oil and natural gas; market uncertainty; weather
conditions in the United States; the condition of the United States economy; the actions of the Organization of
Petroleum Exporting Countries; governmental regulation; political stability in the Middle East and elsewhere; the
foreign supply of oil and natural gas; the price of foreign oil and natural gas imports; the availability of alternate
fuel sources; and transportation interruption. Any substantial and extended decline in the price of oil or natural
gas could have an adverse effect on the carrying value of our proved reserves, borrowing capacity, our ability to
obtain additional capital, and the Company’s revenues, profitability and cash flows from operations.

Volatile oil and natural gas prices make it difficult to estimate the value of producing properties for
acquisition and divestiture and often cause disruption in the market for oil and natural gas producing properties,
as buyers and sellers have difficulty agreeing on such value. Price volatility also makes it difficult to budget for
and project the return on acquisitions and development and exploitation projects.

A substantial portion of our reserves and production is natural gas. Prices for natural gas have been lower
in recent years than at various times in the past and may remain lower in the future. Sustained low prices
for natural gas may also adversely affect our operational and financial condition.

Natural gas prices have been lower in recent years than at various times in the past. These lower prices may
be the result of increased supply resulting from increased drilling in unconventional reservoirs and/or lower
demand resulting from changes in economic activity. Natural gas prices may remain at current levels, or fall to
lower levels, in the future. Approximately 94% of our estimated net proved reserves is natural gas, and 97% of
our production in 2013 was natural gas. Although we expect production operations on properties we currently
own to be profitable at natural gas prices in effect during the past year, a period of sustained low natural gas
prices could have adverse effects on our results of operations and financial condition.

20

Compliance with environmental and other government regulations could be costly and could negatively
impact our production.

Our operations are subject to numerous laws and regulations relating to environmental protection. These

laws and regulations may:

•

•

•

•

require that we acquire permits before developing our properties;

restrict the substances that can be released into the environment in connection with drilling, completion
and production activities;

limit or prohibit drilling activities on protected areas such as wetlands or wilderness areas; and

require remedial measures to mitigate pollution from former operations, such as plugging abandoned
wells.

Under these laws and regulations or under the common law, we could be liable for personal injury and
clean-up costs and other environmental, natural resource and property damages, as well as administrative, civil
and criminal penalties. We could also be affected by more stringent laws and regulations adopted in the future,
including any related to climate change, engine emissions, greenhouse gases and hydraulic fracturing. We
maintain limited insurance coverage for sudden and accidental environmental damages, but do not maintain
insurance coverage for the full potential liability that could be caused by accidental environmental damages.
Accordingly, we may be subject to liability in excess of our insurance coverage or may be required to cease
production from properties in the event of environmental damages.

A significant percentage of our operations are conducted on federal and state lands. These operations are
subject to a wide variety of regulations as well as other permits and authorizations which must be obtained from
and issued by state and federal agencies. To conduct these operations, we may be required to file applications for
permits, seek agency authorizations and comply with various other statutory and regulatory requirements.
Complying with any of these requirements may adversely affect our ability to complete our drilling programs at
the costs and in the time periods anticipated.

Climate change legislation or regulations restricting emissions of “greenhouse gases” (“GHGs”) could
result in increased operating costs and reduced demand for the oil and gas we produce.

More stringent laws and regulations relating to climate change and GHGs may be adopted and could cause
us to incur material expenses to comply. The EPA has adopted rules under the Clean Air Act (“CAA”) for the
permitting of GHG emissions from stationary sources under the Prevention of Significant Deterioration and Title
V permitting programs. These permitting provisions, should they become applicable to our operations, could
require controls or other measures to reduce GHG emissions from new or modified sources, and we could incur
additional material costs to satisfy those requirements.

In addition, on October 30, 2009, the EPA published a final rule requiring the reporting of GHG emissions
from specified large GHG emission sources in the United States beginning in 2011 for emissions occurring in
2010. On November 30, 2010, the EPA published its amendments to the GHG reporting rule to include onshore
and offshore oil and natural gas production facilities and onshore oil and natural gas processing, transmission,
storage and distribution facilities, which may include facilities we operate. Reporting of GHG emissions from
such facilities is required on an annual basis. We will have to incur costs associated with this reporting
obligation.

In addition, the United States Congress has considered legislation to reduce emissions of GHGs and many
states have already taken legal measures to reduce or measure GHG emission levels, often involving the planned
development of GHG emission inventories and/or regional cap and trade programs. Most of these cap and trade
programs require major sources of emissions or major producers of fuels to acquire and surrender emission
allowances. The number of allowances available for purchase is reduced each year in an effort to reduce overall

21

GHG emissions. The cost of these allowances could escalate significantly over time. The adoption and
implementation of any legislation or regulatory programs imposing GHG reporting obligations on, or limiting
emissions of GHGs from, our equipment and operations could require us to incur costs to reduce emissions of
GHGs associated with our operations or could adversely affect demand for the oil and natural gas that we produce.

Potential physical effects of climate change could adversely affect our operations and cause us to incur
significant costs in preparing for or responding to those effects.

In an interpretative guidance on climate change disclosures, the SEC indicates that climate change could
have an effect on the severity of weather (including hurricanes and floods), sea levels, the arability of farmland,
and water availability and quality. If such effects were to occur, our exploration and production operations,
including the hydraulic fracturing of our wells, have the potential to be adversely affected. Potential adverse
effects could include disruption of our production activities, including, for example, damages to our facilities
from powerful winds or increases in our costs of operation or reductions in the efficiency of our operations, as
well as potentially increased costs for insurance coverages in the aftermath of such effects. Significant physical
effects of climate change could also have an indirect effect on our financing and operations by disrupting the
transportation or process related services provided by midstream companies, service companies or suppliers with
whom we have a business relationship. We may not be able to recover through insurance some or any of the
damages, losses or costs that may result from potential physical effects of climate change.

Federal legislation and state legislative and regulatory initiatives relating to hydraulic fracturing could
result in increased costs and additional operating restrictions or delays.

Hydraulic fracturing is used to stimulate production of hydrocarbons, particularly natural gas, from tight
formations. The process involves the injection of water, sand and chemicals under pressure into formations to
fracture the surrounding rock and stimulate production. The process is typically regulated by state oil and gas
commissions but is not subject to regulation at the federal level (except for fracturing activity involving the use
of diesel). The EPA has commenced a study of the potential environmental impacts of hydraulic fracturing
activities, issued a progress report in December 2012, and expects to deliver the final results of the study in 2014.
In addition, in December 2011, the EPA published a draft report in which it asserts that hydraulic fracturing
caused groundwater pollution in a natural gas field in Wyoming (not a field in which we own an interest); this
report has been publicly criticized by industry and by government officials, including the Governor of Wyoming;
it remains subject
to review. A committee of the U.S. House of Representatives is also conducting an
investigation of hydraulic fracturing practices. Legislation was introduced before Congress to provide for federal
regulation of hydraulic fracturing and to require disclosure of the chemicals used in the fracturing process. In
addition, some states have adopted, and other states are considering adopting, regulations that could restrict
hydraulic fracturing in certain circumstances. Pennsylvania has adopted a variety of regulations limiting how and
where fracturing can be performed. Wyoming has adopted regulations requiring us to provide detailed
information about wells we hydraulically fracture in that state. Many other states have adopted or are considering
adopting regulations requiring disclosure of chemicals in fluids used in hydraulic fracturing. Any other new laws
or regulations that significantly restrict hydraulic fracturing could make it more difficult or costly for us to
perform hydraulic fracturing activities and thereby affect our determination of whether a well is commercially
viable. In addition, if hydraulic fracturing is regulated at the federal level, our fracturing activities could become
subject to additional permit requirements or operational restrictions and also to associated permitting delays and
potential increases in costs. We have conducted hydraulic fracturing operations on most of our existing wells,
and we anticipate conducting hydraulic fracturing operations on substantially all of our future wells. As a result,
restrictions on hydraulic fracturing could reduce the amount of oil and natural gas that we are ultimately able to
produce in commercial quantities.

Cyber-attacks targeting systems and infrastructure used by the oil and gas industry may adversely impact
our operations.

Our business has become increasingly dependent on digital technologies to conduct certain exploration,
development, production and financial activities. We depend on digital technology to estimate quantities of oil

22

and gas reserves, process and record financial and operating data, analyze seismic and drilling information, and
communicate with our employees and third party partners. Unauthorized access to our seismic data, reserves
information or other proprietary information could lead to data corruption, communication interruption, or other
operational disruptions in our exploration or production operations. Also, computers control nearly all of the oil
and gas distribution systems in the United States and abroad, which are necessary to transport our production to
market. A cyber-attack directed at oil and gas distribution systems could damage critical distribution and storage
assets or the environment, delay or prevent delivery of production to markets and make it difficult or impossible
to accurately account for production and settle transactions.

While we have not experienced cyber-attacks, there is no assurance that we will not suffer such attacks and
resulting losses in the future. Further, as cyber-attacks continue to evolve, we may be required to expend
significant additional resources to continue to modify or enhance our protective measures or to investigate and
remediate any vulnerability to cyber-attacks.

We may not be able to replace our reserves or generate cash flows if we are unable to purchase or raise
capital. We will be required to make substantial capital expenditures to develop our existing reserves and to
discover new oil and gas reserves.

Our ability to continue exploration and development of our properties and to replace reserves may be
dependent upon our ability to continue to raise significant additional financing, including debt financing or obtain
other potential arrangements with industry partners in lieu of raising financing. Any arrangements that may be
entered into could be expensive to us. There can be no assurance that we will be able to raise additional capital in
light of factors such as the market demand for our securities, the state of financial markets for independent oil
and gas companies (including the markets for debt), oil and natural gas prices and general market conditions. See
“Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and
Capital Resources” for a discussion of our capital budget.

We expect to continue using our bank credit facility to borrow funds to supplement our available cash flow.
The loan commitment and aggregate amount of money we can borrow under the credit facility and from other
sources is revised from time to time based on certain restrictive covenants. A change in our ability to meet the
restrictive covenants might limit our ability to borrow. If this occurred, we may have to sell assets or seek
substitute financing. We can make no assurances that we would be successful in selling assets or arranging
substitute financing. For a description of the bank credit facility and its principal terms and conditions, see
“Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and
Capital Resources.”

Our operations may be interrupted by severe weather or drilling restrictions.

Our operations are conducted primarily in the Rocky Mountain region of the United States and in the north-
central Pennsylvania area of the Appalachian Basin. The weather in these areas can be extreme and can cause
interruption in our exploration and production operations. Severe weather can result in damage to our facilities
entailing longer operational interruptions and significant capital investment. Likewise, our operations are subject
to disruption from winter storms and severe cold, which can limit operations involving fluids and impair access
to our facilities.

Unless we are able to replace reserves that we have produced, our cash flows and production will decrease
over time.

Our future success depends on our ability to find, develop and acquire additional oil and gas reserves that
are economically recoverable. Without successful exploration, development or acquisition activities, our reserves
and production will decline. We can give no assurance that we will be able to find, develop or acquire additional
reserves at acceptable costs.

23

We are exposed to operating hazards and uninsured risks that could adversely impact our results of
operations and cash flow.

The oil and natural gas business involves a variety of operating risks, including blowouts, fire, explosion,
pipe failure, casing collapse, abnormally pressured formations, and environmental hazards such as oil spills,
natural gas leaks, discharges of toxic gases, underground migration and surface spills or mishandling of fracture
fluids, including chemical additives. The occurrence of any of these events with respect to any property we own
or operate (in whole or in part) could have a material adverse impact on us. We and the operators of our
properties maintain insurance in accordance with customary industry practices and in amounts that management
believes to be reasonable. However, insurance coverage is not always economically feasible and is not obtained
to cover all types of operational risks. The occurrence of a significant event that is not fully insured could have a
material adverse effect on our financial condition.

There are risks associated with our drilling activity that could impact our results of operations.

Our oil and natural gas operations are subject to all of the risks and hazards typically associated with
drilling, completion, production and transportation of, oil and natural gas. These risks include the necessity of
spending large amounts of money for identification and acquisition of properties and for drilling and completion
of wells. In the drilling and completing of exploratory or development wells, failures and losses may occur
before any deposits of oil or natural gas are found and produced. The presence of unanticipated pressure or
irregularities in formations, blow-outs or accidents may cause such activity to be unsuccessful, resulting in a loss
of our investment in such activity and possible liabilities. If oil or natural gas is encountered, there can be no
assurance that it can be produced in quantities sufficient to justify the cost of continuing such operations or that it
can be marketed satisfactorily.

Our decision to drill a prospect is subject to a number of factors which may alter our drilling schedule or
our plans to drill at all.

A prospect is an area in which our geoscientists have identified what they believe, based on available
seismic and geological information, to be indications of hydrocarbons. Our prospects are in various stages of
review. Whether or not we ultimately drill our prospects depends on many factors, including but not limited to:
receipt of additional seismic data or reprocessing of existing data; material changes in oil or natural gas prices;
the costs and availability of drilling equipment; success or failure of wells drilled in similar formations or which
would use the same production facilities; the availability and cost of capital; changes in the estimates of costs to
drill or complete wells; decisions of our joint working interest owners; and regulatory and permitting
requirements. It is possible that these factors and others may cause us to alter our drilling schedule or determine
that a prospect should not be pursued at all.

If oil and natural gas prices decrease, we may be required to record additional write downs of the carrying
value of our oil and gas properties.

We follow the full cost method of accounting for our oil and gas properties. A separate cost center is
maintained for expenditures applicable to each country in which we conduct exploration and/or production
activities. Under such method, the net book value of properties on a country-by-country basis, less related
deferred income taxes, may not exceed a calculated “ceiling.” The ceiling is the estimated after tax future net
revenues from proved oil and gas properties, discounted at 10% per year. Discounted future net revenues are
estimated using oil and natural gas spot prices based on the average price during the preceding 12-month period
determined as an unweighted, arithmetic average of the first-day-of-the-month price for each month within such
period, except for changes which are fixed and determinable by existing contracts. The net book value is
compared to the ceiling on a quarterly basis. The excess, if any, of the net book value above the ceiling is
required to be written off as an expense. Under SEC full cost accounting rules, any write-off recorded may not be
reversed even if higher oil and natural gas prices increase the ceiling applicable to future periods. Future price
decreases could result in reductions in the carrying value of such assets and an equivalent charge to earnings.

We have limited control over activities conducted on properties we do not operate.

We own interests in properties that are operated by third parties. The success, timing and costs of drilling,
completion, and other development activities on our non-operated properties depend on a number of factors that
are beyond our control. Because we have only a limited ability to influence and control the operations of our non-
operated properties, we can give no assurances that we will realize our targeted returns with respect to those
properties.

We may fail to fully identify problems with any properties we acquire.

We acquired a portion of our acreage position in Pennsylvania, Utah and Colorado through property
acquisitions and acreage trades, and we may acquire additional acreage in Pennsylvania, Utah or other regions in
the future. Although we conduct a review of properties we acquire which we believe is consistent with industry
practices, we can give no assurance that we have identified or will identify all existing or potential problems
associated with such properties or that we will be able to mitigate any problems we do identify.

There is limited transportation and refining capacity for black wax crude oil produced from our properties
in the Uinta Basin which may limit our ability to sell this production or to increase production in this area.

In December 2013, we acquired oil and gas properties located in the Uinta Basin, Utah. The crude oil these
properties produce is known as black wax crude because it has high paraffin content. Due to this high paraffin
content, transportation options are limited, and most of the oil is transported by truck to refiners in the Salt Lake
City, Utah area. The remainder of the production is transported by rail to markets outside of the Salt Lake City
area.

Market conditions or the unavailability of satisfactory transportation arrangements for this black wax crude
may hinder access to markets or delay production. Without additional refining capacity or access to additional
markets for such production, our ability to increase production from the Uinta Basin may be constrained. Limited
refinery capacities in the Utah region, coupled with the potential for increased production in the Uinta Basin,
may impact local marketability of a portion of our Utah oil and may cause us to pursue alternate transportation
methods and sales outlets, such as rail transportation to markets on the east and west coasts, as well as in the mid-
continent. Although several refinery expansions have been announced or are underway in the Salt Lake City area
to accept additional black wax crude, there is no assurance as to the ultimate added capacity, our ability to access
any such capacity, or the timing of completion of such expansions.

We may not be successful in securing alternative sales outlets for our Utah production. The availability of a
ready market depends on a number of factors, including the general demand for and supply of oil and the
proximity of alternative reserves to pipelines, rail transportation and terminal facilities. Our ability to market our
black wax crude production will depend in substantial part on the availability and capacity of trucking and rail
systems servicing the Uinta Basin and refineries capable of handling high paraffin crude, all of which are owned
and operated by third parties. We may be required to shut in wells for a lack of a market or because of
inadequacy or unavailability of such markets or related transportation. Decreased access to oil markets or access
to such markets on unacceptable terms could result in increased costs, decreased margins, decreased production,
or other factors which could materially and adversely affect our business, financial condition and results of
operations and operating cash flows.

Item 2. Properties.

Location and Characteristics

The Company owns oil and natural gas leases in Wyoming, Pennsylvania and Utah and oil and gas leases
and fee minerals in Colorado. The leases in Wyoming are primarily federal leases with 10-year lease terms until
establishment of production. Production extends the lease terms until cessation of that production. In
Pennsylvania, the leases are from private individuals and companies, as well as from the Commonwealth of
Pennsylvania. The Pennsylvania leases are mostly undeveloped at this time and typically have primary lease
terms of five years until establishment of production. The leases in Utah are from private individuals and
companies, the State of Utah, and the federal government and are mostly undeveloped at this time with primary
lease terms ranging from five to ten years until the establishment of production. The Company also owns
undeveloped acreage in Colorado with no immediate plans for further exploration in this area in 2014.

Green River Basin, Wyoming

As of December 31, 2013,

the Company owned oil and natural gas leases totaling approximately
84,000 gross (49,000 net) acres in southwest Wyoming’s Green River Basin. Most of this acreage covers the
Pinedale and Jonah fields. Of the total acreage position in Wyoming, approximately 22,000 gross (10,000 net)
acres were developed, and 62,000 gross (39,000 net) acres were undeveloped. The developed portion represents
13% of the Company’s total developed net acreage while the undeveloped portion represents approximately 11%
of the Company’s total undeveloped net acreage.

Lease maintenance costs in Wyoming were approximately $0.2 million for the year ended December 31,
2013. The Company currently owns 58 leases totaling 69,000 gross (37,000 net) acres that are held by production
and activities (“HBP”). The HBP acreage includes all of the Company’s leases within the productive area of the
Pinedale and Jonah fields.

Development Wells. During 2013,

the Company participated in the drilling of 58 gross (23.2 net)
productive development wells on the Green River Basin properties. At year-end 2013, there were 5 gross (4.0
net) additional development wells that commenced during the year and were either still drilling or had operations
suspended at a depth short of total depth.

Exploratory Wells. During 2013, the Company participated in the drilling of a total of 55 gross (31.1 net)
productive exploratory wells on the Green River Basin properties. At December 31, 2013, there were 11 gross
(5.8 net) additional exploratory wells that commenced during the year that were either still drilling or had
operations suspended at a depth short of total depth and thus a determination of productive capability could not
be made at year-end.

Seismic Activity. The Company’s 3D seismic coverage in Wyoming totals approximately 253 square
miles. The data has all been licensed from independent seismic contractors, and provides coverage over the entire
productive area of the Pinedale field.

Pennsylvania

As of December 31, 2013, the Company owned oil and gas leases covering 473,000 gross (250,000 net)
acres in the Pennsylvania portion of the Appalachian Basin. This acreage is located in the heart of northeast
Pennsylvania’s Marcellus Shale Gas Trend, principally in Potter, Tioga, Lycoming, Centre and Clinton counties.
Of the total acreage position as of December 31, 2013, approximately 119,000 gross (63,000 net) acres were
developed, and 354,000 gross (187,000 net) acres were undeveloped. The developed portion represents 84% of
the Company’s total developed net acreage position while the undeveloped portion represents 51% of the
Company’s total undeveloped net acreage position. The Company operates approximately 96,000 gross (64,000
net) acres of the total position.

27

Lease maintenance costs in Pennsylvania were approximately $0.9 million for the year ended December 31,
2013. The Company owns approximately 345,000 gross (181,000 net) acres currently held by production or
activities in Pennsylvania.

Exploratory Wells. During the year ended December 31, 2013, the Company participated in the drilling of
a total of 20 gross (9.9 net) productive exploratory wells on the Pennsylvania properties. At December 31, 2013,
there were no additional exploratory wells that commenced during the year that were either still drilling or had
operations suspended at a depth short of total depth and thus a determination of productive capability could not
be made at year-end.

Seismic Activity. The Company’s total 3D seismic coverage in Pennsylvania is approximately 505 square
miles. Of this total, 433 square miles of data is jointly owned with other parties, 30 square miles is owned solely
by the Company, and 42 square miles are licensed from a third party.

Uinta Basin, Utah

As of December 31, 2013, the Company owned oil and natural gas leases covering 8,000 gross (8,000 net)
acres in the Utah portion of the Green River Basin. This acreage is located in Uintah County in the eastern
portion of the Uinta Basin. As of December 31, 2013, approximately 2,000 gross (2,000 net) acres were
developed, and 6,000 gross (6,000 net) acres were undeveloped. The developed portion represents 3% of the
Company’s total developed net acreage position while the undeveloped portion represents 2% of the Company’s
total undeveloped net acreage position. The Company operates 100% of the properties.

There were no lease maintenance costs in Utah for the year ended December 31, 2013. The Company owns

approximately 6,000 gross (6,000 net) acres currently held by production or activities in Utah.

Exploratory Wells. During the period from the closing of the acquisition through December 31, 2013, the
Company participated in the drilling of a total of 2 gross (2.0 net) productive exploratory wells on the Utah
properties. At December 31, 2013, there was 1 gross (1.0 net) additional exploratory well that commenced during
the year that was either still drilling or had operations suspended at a depth short of total depth and thus a
determination of productive capability could not be made at year-end.

Seismic Activity. The Company currently does not own any seismic data over its Utah properties.

(1) Oil and condensate are converted to natural gas at the ratio of one barrel of oil or condensate to six Mcf of
natural gas. This conversion ratio, which is typically used in the oil and gas industry, represents the
approximate energy equivalent of a barrel of oil or condensate to an Mcf of natural gas. The sales price of
one barrel of oil or condensate has been much higher than the sales price of six Mcf of natural gas over the
last several years, so a six to one conversion ratio does not represent the economic equivalency of six Mcf of
natural gas to one barrel of oil or condensate.

(2) Management believes that the presentation of the standardized measure of discounted future net cash flows,
before income taxes, of estimated proved reserves, discounted at 10% per annum, may be considered a non-
Generally Accepted Accounting Principle financial measure as defined in Item 10(e) of Regulation S-K,
therefore the Company has included this reconciliation of the measure to the most directly comparable
Generally Accepted Accounting Principle (“GAAP”) financial measure (standardized measure of discounted
future net cash flows, after income taxes). Management believes that the presentation of the standardized
measure of future net cash flows before income taxes provides useful information to investors because it is
widely used by professional analysts and sophisticated investors in evaluating oil and gas companies.
Because many factors that are unique to each individual company may impact the amount of future income
taxes to be paid, the use of the pre-tax measure provides greater comparability when evaluating companies.
It is relevant and useful to investors for evaluating the relative monetary significance of the Company’s oil
and natural gas properties. Further, investors may utilize the measure as a basis for comparison of the
relative size and value of the Company’s reserves to other companies. The standardized measure of
discounted future net cash flows, before income taxes,
is not a measure of financial or operating
performance under GAAP, nor is it intended to represent the current market value of the estimated oil and
natural gas reserves owned by the Company. Standardized measure of discounted future net cash flows,
before income taxes, should not be considered in isolation or as a substitute for the standardized measure of
discounted future net cash flows as defined under GAAP.

Since January 1, 2013, no crude oil or natural gas reserve information has been filed with, or included in any
report to, any federal authority or agency other than the SEC and the Energy Information Administration (“EIA”)
of the U.S. Department of Energy. We file Form 23, including reserve and other information, with the EIA.

In 2013, the Company converted 130.5 Bcfe of proved undeveloped reserves to proved developed reserves.
All of these conversions were located in the Pinedale field in Wyoming. During 2013, the Company spent $102.3
million to convert proved undeveloped reserves to proved developed reserves. At December 31, 2013, the
Company also transferred 667.2 Bcfe of proved undeveloped reserves to the unproven category of reserves due to
adjustments to the Company’s 5-year development plan. In response to higher gas prices, the Company increased
the capital scheduled for proved undeveloped locations from $1.4 billion at December 31, 2012 to $1.8 billion at
December 31, 2013. The Company has not scheduled any proved undeveloped reserves beyond five years nor
does it have any proved undeveloped locations that have been part of its inventory of proved undeveloped
locations for over five years. Nearly all of the future proved undeveloped locations are located in Pinedale.

Internal Controls Over Reserve Estimating Process

Our policies and practices regarding internal controls over the recording of reserves is structured to
objectively and accurately estimate our oil and gas reserve quantities and present values in compliance with the
SEC’s regulations and GAAP. The Vice President — Reservoir Engineering & Development is primarily
responsible for overseeing the preparation of the Company’s reserve estimates. He has a Bachelor and Master of
Science degree in Petroleum Engineering and is a licensed Professional Engineer with over 19 years of
experience. The Company’s internal controls over reserve estimates include reconciliation and review controls,
including an independent internal review of assumptions used in the estimation.

The estimates of proved reserves and future net revenue as of December 31, 2013 are based upon the use of
technical and economic data including, but not limited to, well logs, geologic maps, seismic data, well test data,
production data, historical price and cost information and property ownership interests. The reserves were
estimated using deterministic methods; these estimates were prepared in accordance with generally accepted
petroleum engineering and evaluation principles. Standard engineering and geoscience methods, such as
reservoir modeling, performance analysis, volumetric analysis and analogy,
that were considered to be
appropriate and necessary to establish reserve quantities and reserve categorization that conform to SEC
definitions and rules and regulations, were also used. As in all aspects of oil and natural gas evaluation, there are
uncertainties inherent
these estimates
necessarily represent only informed professional judgment.

in the interpretation of engineering and geoscience data;

therefore,

The Company engaged Netherland, Sewell & Associates, Inc. (“NSAI”), a third-party,

independent
engineering firm, to prepare the reserve estimates for all of the Company’s assets in Wyoming and Pennsylvania

30

for the year ended December 31, 2013 in this annual report. This independent analysis conducted by NSAI
represents more than 98% of the Company’s proved reserves. Our internal professional staff works closely with
our independent engineers, NSAI, to ensure the integrity, accuracy and timeliness of data that is furnished to
them for their reserve estimation process. In addition, other pertinent data is provided such as seismic
information, geologic maps, well logs, production tests, well performance data, operating procedures and
relevant economic criteria. We make available all information requested, including our pertinent personnel, to the
external engineers as part of their evaluation of our reserves. The report of NSAI is included as an Exhibit to this
annual report.

The majority of reserve estimates shown herein have been independently evaluated by Netherland, Sewell &
Associates, Inc. (NSAI), a worldwide leader of petroleum property analysis for industry and financial
organizations and government agencies. NSAI was founded in 1961 and performs consulting petroleum
engineering services under Texas Board of Professional Engineers Registration No. F-2699. Within NSAI, the
technical persons primarily responsible for preparing the estimates set forth in the NSAI reserves report
incorporated herein are Mr. Robert C. Barg and Mr. Phillip R. Hodgson. Mr. Barg has been practicing consulting
petroleum engineering at NSAI since 1989. Mr. Barg is a Licensed Professional Engineer in the State of Texas
(No. 71658) and has over 30 years of practical experience in petroleum engineering, with over 24 years’
experience in the estimation and evaluation of reserves. He graduated from Purdue University in 1983 with a
Bachelor of Science Degree in Mechanical Engineering. Mr. Hodgson has been practicing consulting petroleum
geology at NSAI since 1998. Mr. Hodgson is a Licensed Professional Geoscientist in the State of Texas, Geology
(No. 1314) and has over 29 years of practical experience in petroleum geosciences, with over 15 years’
experience in the estimation and evaluation of reserves. He graduated from University of Illinois in 1982 with a
Bachelor of Science Degree in Geology and from Purdue University in 1984 with a Master of Science Degree in
Geophysics. Both technical principals meet or exceed the education, training, and experience requirements set
forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information
promulgated by the Society of Petroleum Engineers; both are proficient in judiciously applying industry standard
practices to engineering and geoscience evaluations as well as applying SEC and other industry reserves
definitions and guidelines.

The Company closed on its acquisition of assets in Utah on December 12, 2013. Due to the timing of this
acquisition relative to the timing of preparing annual corporate reserves, the Company’s Reservoir Engineering
Department prepared the proved reserve estimates for its Utah assets. The proved reserve estimates were
prepared in accordance with the Company’s internal controls and SEC regulations. Furthermore, the reserves
estimated for the Utah assets are limited to proved developed wells as of December 31, 2013 and represent less
than 2% of our estimated proved reserves as of December 31, 2013.

Delivery Commitments

With respect to the Company’s natural gas production, from time to time the Company enters into
transactions to deliver specified quantities of gas to its customers. As of February 8, 2014, the Company has
long-term natural gas delivery commitments of 41.6 MMMBtu in 2014, 26.5 MMMBtu in 2015, 6.0 MMMBtu in
2016, and 7.9 MMMBtu in 2017 under existing agreements. As of February 8, 2014, the Company has long-term
crude oil delivery commitments of 1.6 MBbls in 2014, 1.8 MBbls in 2015, 1.8 MBbls in 2016, 1.5 MBbls in
2017 and 1.2 MBbls beyond 5 years under existing agreements. None of these commitments require the
Company to deliver gas or oil produced specifically from any of the Company’s properties, and all of these
commitments are priced on a floating basis with reference to an index price.

These amounts are well below the Company’s forecasted 2014 and anticipated 2015 through 2018
production from its available reserves. In addition, none of the Company’s reserves are subject to any priorities
or curtailments that may affect quantities delivered to its customers, any priority allocations or price limitations
imposed by federal or state regulatory agencies or any other factors beyond the Company’s control that may
affect its ability to meet its contractual obligations other than those discussed in Item 1A. “Risk Factors”. The
Company believes that its production and reserves are adequate to meet its delivery commitments. If for some
reason the Company’s production is not sufficient to satisfy its delivery commitments, the Company expects to
be able to purchase natural gas volumes in the market to satisfy its commitments.

Productive Wells

As of December 31, 2013 the Company’s total gross and net wells were as follows:

* Productive wells are producing wells, shut-in wells the Company deems capable of production, wells that are
waiting for completion, plus wells that are drilled/cased and completed, but waiting for pipeline hook-up. A
gross well is a well in which a working interest is owned. The number of net wells represents the sum of
fractional working interests the company owns in gross wells.

Oil and Gas Acreage

The primary terms of the Company’s oil and gas leases expire at various dates. Much of the Company’s
undeveloped acreage is held by production, which means that the Company will maintain its rights in these leases
as long as oil or natural gas is produced from the acreage by it or by other parties holding interests in producing
wells on those leases. In some cases, if production from a lease ceases, the lease will expire, and in some cases, if
production from a lease ceases, the Company may maintain the lease by additional operations on the acreage.

The Company does not believe the remaining terms of its leases is material. At December 31, 2013, the
Company had 7,000 net acres of leases in Pennsylvania, 80,000 net acres of leases in Colorado, 150 net acres of
leases in Utah and no leases in Wyoming that expire in 2014. The Company has no immediate plans for further
development of the Colorado leasehold in 2014, and expects to maintain all of the Utah leases and approximately
15% of Pennsylvania leases by production, operations, extensions or renewals. The Company does not expect to
lose material lease acreage because of failure to drill due to inadequate capital, equipment or personnel. The
Company has, based on its evaluation of prospective economics, allowed acreage to expire and it may allow
additional acreage to expire in the future.

Item 7. — Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of the financial condition and operating results of the Company should be read in
conjunction with the consolidated financial statements and related notes of the Company, which are included in
this report in Item 8, and the information set forth in Risk Factors under Item 1A. Except as otherwise indicated,
all amounts are expressed in U.S. dollars.

Overview

Ultra Petroleum Corp. is an independent exploration and production company focused on developing its
long-life natural gas reserves in the Green River Basin of Wyoming — the Pinedale and Jonah fields — and is in
the early exploration and development stages in the Uinta Basin in Utah and the Appalachian Basin of
Pennsylvania. The Company operates in one industry segment, natural gas and oil exploration and development,
with one geographical segment, the United States.

The Company currently conducts operations exclusively in the United States. Substantially all of its oil and
natural gas activities are conducted jointly with others and, accordingly, amounts presented reflect only the
Company’s proportionate interest in such activities. Inflation has not had a material impact on the Company’s
results of operations. The Company continues to focus on improving its drilling and production results through
gaining efficiencies with the use of advanced technologies, detailed technical analysis of its properties and
leveraging its experience into improved operational efficiencies. Inflation is not expected to have a material
impact on the Company’s results of operations in the future.

The Company currently generates its revenue, earnings and cash flow primarily from the production and
sales of natural gas and condensate from its properties in southwest Wyoming with an increasing portion of the
Company’s revenues coming from gas sales from wells located in the Appalachian Basin in Pennsylvania. In
December 2013, the Company acquired properties in the Uinta Basin in Utah which primarily produce oil.

The price of natural gas is a critical factor to the Company’s business and the price of natural gas has
historically been volatile, and its volatility could be detrimental to the Company’s financial performance. As a
result, and from time to time, the Company tries to limit the impact of this volatility on its results by entering into
swap agreements and/or fixed price forward physical delivery contracts for natural gas. (See Note 7).

The average price realization for the Company’s natural gas during 2013 was $3.57 per Mcf, including
realized gains and losses on commodity derivatives. During the quarter ended December 31, 2013, the average
price realization for the Company’s natural gas was $3.58 per Mcf, including realized gains and losses on
commodity derivatives. The Company’s average price realization for natural gas, excluding realized gains and
losses on commodity derivatives, was $3.66 per Mcf and $3.57 per Mcf for the year and quarter ended
December 31, 2013, respectively.

Mission and Strategy

Ultra’s mission is to profitably grow an upstream oil and gas company for the long-term benefit of its
shareholders. Ultra’s strategy to achieve this goal includes building a portfolio of high return investment
opportunities, maintaining a disciplined approach to capital investment, maximizing earnings and cash flows by
controlling costs and maintaining financial flexibility.

High Return Portfolio. Ultra seeks to maintain a portfolio of properties that provide long-term, profitable
growth through development in areas that support sustainable,
lower-risk, repeatable, high return drilling
projects. The Company continually evaluates opportunities for the acquisition, exploration and development of
additional oil and natural gas properties that afford risk-adjusted returns in excess of or equal to its current set of
investment alternatives.

39

Disciplined Capital Investment. Part of the Company’s business strategy includes proactive and regular
review of its portfolio of investment opportunities with a focus on investments that produce positive returns in
order to optimize return to its shareholders. Accordingly, in response to the low natural gas price environment in
2012 and 2013, the Company reduced capital expenditures by reducing the number of drilling rigs operating in
its Wyoming fields and encouraged the parties operating projects on its behalf in Pennsylvania to reduce their
activity as well. Reductions in the Company’s activity resulted in reduced capital spending during the current
year as compared to the prior year. The Company actively seeks to identify additional investment opportunities
that have the ability to profitably grow its business while diversifying its portfolio and leveraging its expertise in
unconventional reservoirs as a low cost operator. The Company actively works to identify appropriate entry
points into these opportunities through either grass root development or acquisitions. Accordingly, the Company
closed on the acquisition of crude oil assets in Three Rivers Field in the Uinta Basin in Utah. The acquisition
leverages the Company’s technical expertise as the Uinta Basin has similar tight-sand geologic characteristics to
the Pinedale Field, and the Company considers the returns associated with the Utah acquisition to be competitive
with its current investment portfolio.

Focus on Costs. Ultra strives to maintain one of the lowest cost structures in the industry in terms of both
adding and producing oil and natural gas reserves. The Company continues to focus on improving its drilling and
production results through the use of advanced technologies and detailed technical analysis of its properties.

Financial Strength and Flexibility. Preserving financial flexibility and a strong balance sheet are also
strategic to Ultra’s business philosophy. Maintaining financial discipline enables the Company to capitalize on
the flexibility of its portfolio.

Critical Accounting Policies

The discussion and analysis of the Company’s financial condition and results of operations is based upon
consolidated financial statements, which have been prepared in accordance with U.S. GAAP. In addition,
application of GAAP requires the use of estimates, judgments and assumptions that affect the reported amounts
of assets and liabilities as of the date of the financial statements as well as the revenues and expenses reported
during the period. Changes in these estimates related to judgments and assumptions will occur as a result of
future events, and, accordingly, actual results could differ from amounts estimated. Set forth below is a
discussion of the critical accounting policies used in the preparation of our financial statements which we believe
involve the most complex or subjective decisions or assessments.

Oil and Gas Reserves. The reserve estimates presented herein were made in accordance with oil and gas
reserve estimation and disclosure authoritative accounting guidance according to Financial Accounting Standards
Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 932, Extractive Activities — Oil and Gas
(“FASB ASC 932”) as updated in order to align the reserve calculation and disclosure requirements with those in
SEC Release No. 33-8995.

The Company utilizes reliable technology such as seismic data and interpretation, wireline formation tests,
geophysical logs and core data to assess its resources. However, none of these technologies have contributed to a
material addition to the proved reserves in this report.

Estimates of proved crude oil and natural gas reserves significantly affect the Company’s depreciation,
depletion and amortization (“DD&A”) expense. For example, if estimates of proved reserves decline, the
Company’s DD&A rate will increase, resulting in a decrease in net income. A decline in estimates of proved
reserves may result from a number of factors including lower prices, evaluation of additional operating history,
mechanical problems on our wells and catastrophic events. Lower prices also make it uneconomical to drill wells
or produce from fields with high operating costs.

The Company’s proved reserves are a function of many assumptions, all of which could deviate materially
from actual results. As a result, the estimates of proved reserves could vary over time, and could vary from actual
results.

40

Full Cost Method of Accounting. The Company uses the full cost method of accounting for oil and gas
exploration and development activities as defined by SEC Release No. 33-8995 and FASB ASC 932. Under the
full cost method of accounting, all costs associated with the exploration for and development of oil and gas
reserves are capitalized on a country-by-country basis. All costs incurred in the acquisition, exploration and
development of properties (including costs of surrendered and abandoned leaseholds, delay lease rentals, dry
holes and overhead related to exploration and development activities) are capitalized. The sum of net capitalized
costs and estimated future development costs of oil and natural gas properties for each full cost center are
depleted using the units-of-production method. Changes in estimates of proved reserves, future development
costs or asset retirement obligations are accounted for prospectively in our depletion calculation.

Under the full cost method, costs of unevaluated properties and major development projects expected to
require significant future costs may be excluded from capitalized costs being amortized. The Company excludes
significant costs until proved reserves are found or until it is determined that the costs are impaired. Excluded
costs, if any, are reviewed quarterly to determine if impairment has occurred. The amount of any impairment is
transferred to the capitalized costs being amortized in the appropriate full cost pool.

Write-down of Oil and Gas Properties. Companies that use the full cost method of accounting for oil and
natural gas exploration and development activities are required to perform a ceiling test calculation each quarter.
The full cost ceiling test is an impairment test prescribed by SEC Regulation S-X Rule 4-10. The ceiling test is
performed quarterly, on a country-by-country basis, utilizing the average of prices in effect on the first day of the
month for the preceding twelve month period. The ceiling limits such pooled costs to the aggregate of the present
value of future net revenues attributable to proved crude oil and natural gas reserves discounted at 10% plus the
lower of cost or market value of unproved properties less any associated tax effects. If such capitalized costs
exceed the ceiling, the Company will record a write-down to the extent of such excess as a non-cash charge to
earnings. Any such write-down will reduce earnings in the period of occurrence and result in a lower DD&A rate
in future periods. A write-down may not be reversed in future periods even though higher oil and natural gas
prices may subsequently increase the ceiling.

The calculation of the ceiling test is based upon estimates of proved reserves. There are numerous
uncertainties inherent in estimating quantities of proved reserves, in projecting the future rates of production and
in the timing of development activities. The accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation and judgment. Results of drilling, testing and
production subsequent to the date of the estimate may justify revision of such estimate. Accordingly, reserve
estimates are often different from the quantities of oil and natural gas that are ultimately recovered.

During 2012, the Company recorded a $2.9 billion non-cash write-down of the carrying value of the
Company’s proved oil and gas properties as a result of ceiling test limitations, which is reflected with ceiling test
and other impairments in the accompanying Consolidated Statements of Operations. The ceiling test was
calculated based upon the average of quoted market prices in effect on the first day of the month for the
preceding twelve month period at December 31, 2012, September 30, 2012 and June 30, 2012 for Henry Hub
natural gas and West Texas Intermediate oil, adjusted for market differentials. The Company did not have any
write-downs related to the full cost ceiling limitation in 2013 or 2011.

Asset Retirement Obligation. The Company’s asset retirement obligations (“ARO”) consist primarily of
estimated costs of dismantlement, removal, site reclamation and similar activities associated with its oil and
natural gas properties. FASB ASC Topic 410, Asset Retirement and Environmental Obligations (“FASB ASC
410”) requires that the discounted fair value of a liability for an ARO be recognized in the period in which it is
incurred with the associated asset retirement cost capitalized as part of the carrying cost of the oil and natural gas
asset. The recognition of an ARO requires that management make numerous estimates, assumptions and
judgments regarding such factors as the existence of a legal obligation for an ARO, estimated probabilities,
amounts and timing of settlements; the credit-adjusted, risk-free rate to be used; inflation rates, and future
advances in technology. In periods subsequent to initial measurement of the ARO, the Company must recognize

41

period-to-period changes in the liability resulting from the passage of time and revisions to either the timing or
the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to passage of
time impact net income as accretion expense. The related capitalized costs, including revisions thereto, are
charged to expense through DD&A.

Entitlements Method of Accounting for Oil and Natural Gas Sales. The Company generally sells natural
gas and condensate under both long-term and short-term agreements at prevailing market prices and under multi-
year contracts that provide for a fixed price of oil and natural gas. The Company recognizes revenues when the
oil and natural gas is delivered, which occurs when the customer has taken title and has assumed the risks and
rewards of ownership, prices are fixed or determinable and collectability is reasonably assured. The Company
accounts for oil and natural gas sales using the “entitlements method.” Under the entitlements method, revenue is
recorded based upon the Company’s ownership share of volumes sold, regardless of whether it has taken its
ownership share of such volumes. The Company records a receivable or a liability to the extent it receives less or
more than its share of the volumes and related revenue.

Make-up provisions and ultimate settlements of volume imbalances are generally governed by agreements
between the Company and its partners with respect to specific properties or, in the absence of such agreements,
through negotiation. The value of volumes over- or under-produced can change based on changes in commodity
prices. The Company prefers the entitlements method of accounting for oil and natural gas sales because it allows
for recognition of revenue based on its actual share of jointly owned production, results in better matching of
revenue with related operating expenses, and provides balance sheet recognition of the estimated value of
product imbalances.

Valuation of Deferred Tax Assets. The Company uses the asset and liability method of accounting for
income taxes. Under this method, future income tax assets and liabilities are determined based on differences
between the financial statement carrying values and their respective income tax basis (temporary differences).

To assess the realization of deferred tax assets, management considers whether it is more likely than not that
some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in which those temporary differences
become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future
taxable income and tax planning strategies in making this assessment.

As a result of the tax effect of the ceiling test and other impairments recorded during the year ended
December 31, 2012, the Company’s previously recorded net deferred tax liability fully reversed into a net
deferred tax asset. The Company has recorded a full valuation allowance against its net deferred tax asset balance
of $363.4 million as of December 31, 2013. This valuation allowance may be reversed in future periods against
future income.

Derivative Instruments and Hedging Activities. The Company follows FASB ASC Topic 815,
Derivatives and Hedging (“FASB ASC 815”). The Company records the fair value of its commodity derivatives
as an asset or liability on the Consolidated Balance Sheets, and records the changes in the fair value of its
commodity derivatives in the Consolidated Statements of Operations as an unrealized gain or loss on commodity
derivatives.

Fair Value Measurements. The Company follows FASB ASC Topic 820, Fair Value Measurements and
Disclosures (“FASB ASC 820”). Under FASB ASC 820, fair value is defined as the price that would be received
to sell an asset or paid to transfer a liability in an orderly transaction between market participants at measurement
date and establishes a three level hierarchy for measuring fair value. The valuation assumptions the Company has
used to measure the fair value of its commodity derivatives were observable inputs based on market data
obtained from independent sources and are considered Level 2 inputs (quoted prices for similar assets, liabilities
(adjusted) and market-corroborated inputs). See Note 8 for additional information.

42

In consideration of counterparty credit risk,

the Company assessed the possibility of whether each
counterparty to the derivative would default by failing to make any contractually required payments as scheduled
in the derivative instrument in determining the fair value. Additionally, the Company considers that it is of
substantial credit quality and has the financial resources and willingness to meet its potential repayment
obligations associated with the derivative transactions.

Legal, Environmental and Other Contingencies. A provision for legal, environmental and other
contingencies is charged to expense when the loss is probable and the cost can be reasonably estimated.
Determining when expenses should be recorded for these contingencies and the appropriate amounts for accrual
is a complex estimation process that
includes the subjective judgment of management. In many cases,
management’s judgment is based on interpretation of laws and regulations, which can be interpreted differently
by regulators and/or courts of law. The Company’s management closely monitors known and potential legal,
environmental and other contingencies and periodically determines when the Company should record losses for
these items based on information available to the Company.

Share-Based Payment Arrangements. The Company follows FASB ASC Topic 718, Compensation —
Stock Compensation (“FASB ASC 718”) which requires the measurement and recognition of compensation
expense for all share-based payment awards made to employees and directors, including employee stock options,
based on estimated fair values. Share-based compensation expense recognized under FASB ASC 718 for the
years ended December 31, 2013, 2012 and 2011 was $9.8 million, $10.8 million and $13.9 million, respectively.
See Note 6 for additional information.

Conversion of Barrels of Oil to Mcfe of Gas. The Company converts Bbls of oil and other liquid
hydrocarbons to Mcfe at a ratio of one Bbl of oil or liquids to six Mcfe. This conversion ratio, which is typically
used in the oil and gas industry, represents the approximate energy equivalent of a barrel of oil or other liquids to
an Mcf of natural gas. The sales price of one Bbl of oil or liquids has been much higher than the sales price of six
Mcf of natural gas over the last several years, so a six to one conversion ratio does not represent the economic
equivalency of six Mcf of natural gas to a Bbl of oil or other liquids.

Recent Accounting Pronouncements.

In January 2013, the FASB issued Accounting Standards Update
No. 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and
Liabilities (“Update 2013-01”), which finalizes Proposed ASU No. 2012-250 and clarifies the scope of
transactions that are subject to disclosures concerning offsetting. Update 2013-01 addresses implementation
issues regarding the scope of ASU No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets
and Liabilities, issued in December 2011. Update 2013-01 clarifies that the scope of the disclosures under U.S.
GAAP is limited to derivatives, repurchase agreements and reverse purchase agreements, and securities
borrowing and securities lending transactions that are offset either in accordance with FASB ASC Section 210-
20-45, Balance Sheet — Offsetting — Other Presentation Matters, or FASB ASC Section 815-10-45, Derivatives
and Hedging — Overall — Other Presentation Matters, or are subject to a master netting arrangement or similar
agreement. Update 2013-01 requires an entity (1) to apply the amendments for annual reporting periods
beginning on or after January 1, 2013 and (2) to provide the required disclosures retrospectively for all
comparative periods presented. The implementation of the disclosure requirement did not have a material impact
on the Company’s consolidated results of operations, financial position or cash flows.

Production, Commodity Prices and Revenues:

Production. During the year ended December 31, 2013, production decreased on a gas equivalent basis to
232.1 Bcfe from 257.0 Bcfe for the same period in 2012 as a result of decreased capital spending in response to
reduced natural gas prices.

Commodity prices. Realized natural gas prices, including realized gain and loss on commodity derivatives,
decreased to $3.57 per Mcf during the year ended December 31, 2013 as compared to $4.01 per Mcf during 2012.
During the year ended December 31, 2013, the Company’s average price for natural gas was $3.66 per Mcf, excluding
realized gains and losses on commodity derivatives, as compared to $2.79 per Mcf for the same period in 2012.

Revenues. The increase in average natural gas prices, excluding the effects of commodity derivatives,
largely contributed to a 15% increase in revenues for the year ended December 31, 2013 to $933.4 million as
compared to $810.0 million in 2012.

44

Operating Costs and Expenses:

Lease Operating Expense. Lease operating expenses (“LOE”) increased to $68.1 million for the year
ended December 31, 2013 compared to $63.8 million during the same period in 2012 primarily due to increased
well counts. On a unit of production basis, LOE costs increased to $0.29 per Mcfe at December 31, 2013
compared to $0.25 per Mcfe at December 31, 2012 as a result of decreased production volumes and increase
costs during the period ended December 31, 2013.

Operating Lease Expense. During December 2012, the Company sold a system of liquids gathering
pipelines and central gathering facilities (the “LGS”) and certain associated real property rights in the Pinedale
Anticline in Wyoming. The Company entered into a long-term, triple net lease agreement with the buyer relating
to the use of the LGS (the “Lease Agreement”). The Lease Agreement provides for an initial term of 15 years,
and annual rent for the initial term under the Lease Agreement is $20.0 million (as adjusted annually for changes
based on the consumer price index) and may increase if certain volume thresholds are exceeded. The lease is
classified as an operating lease. For the year ended December 31, 2013, the Company recognized operating lease
expense associated with the Lease Agreement of $20.0 million, or $0.09 per Mcfe.

Production Taxes. During the year ended December 31, 2013, production taxes were $72.4 million
compared to $60.8 million during the same period in 2012, or $0.31 per Mcfe, compared to $0.24 per Mcfe.
Production taxes are primarily calculated based on a percentage of revenue from production in Wyoming after
certain deductions and were 7.8% of revenues for the year ended 2013 and 7.5% for the same period in 2012. The
increase in per unit taxes is primarily attributable to increased sales revenues as a result of increased natural gas
prices, excluding the effects of commodity derivatives, during the year December 31, 2013 as compared to the
same period in 2012.

Gathering Fees. Gathering fees decreased to $52.1 million for the year ended December 31, 2013
compared to $59.0 million during the same period in 2012 largely due to ownership participation in the Anadarko
gathering system beginning in the second quarter of 2012 as well as a higher percentage of production in
Pennsylvania in areas where the Company does not incur third party gathering fees. On a per unit basis, gathering
fees were $0.22 per Mcfe for the year ended December 31, 2013 as compared to $0.23 for the period ended
December 31, 2012.

Transportation Charges. The Company incurred firm transportation charges totaling $82.8 million for the
year ended December 31, 2013 as compared to $84.5 million for the same period in 2012 in association with
REX pipeline charges. On a per unit basis, transportation charges increased to $0.36 per Mcfe (on total company
volumes) for the year ended December 31, 2013 as compared to $0.33 for the same period in 2012 primarily due
to decreased production volumes during the year ended December 31, 2013.

Depletion, Depreciation and Amortization. DD&A expenses decreased to $243.4 million during the year
ended December 31, 2013 from $389.0 million for the same period in 2012. Of this decrease, $119.4 million was
attributable to a lower depletion rate due to a lower depletable base as a result of the ceiling test write-downs
during the year ended December 31, 2012 and $26.2 million was attributable to decreased production volumes
during the year ended December 31, 2013. On a unit of production basis, DD&A decreased to $1.05 per Mcfe at
December 31, 2013 from $1.51 at December 31, 2012.

Impairment Charges. The Company did not have any write-downs related to the full cost ceiling limitation
during the period ended December 31, 2013 compared with a $2.9 billion non-cash write-down of the carrying
value of its proved oil and natural gas properties for the year ended December 31, 2012. In addition, the
Company recognized impairments of $92.5 million during the year ended December 31, 2012 related to the
decline in fair value as defined in FASB ASC 820 as a result of forecast decreased throughput volumes on its
gathering facilities in Pennsylvania due to the decline in commodity prices. (See Note 8 for additional
information on fair value).

45

General and Administrative Expenses. General and administrative expenses decreased to $22.4 million for
the period ended December 31, 2013 compared to $25.1 million for the same period in 2012. The decrease in
general and administrative expenses is largely attributable to lower employee-related and consultant costs. On a
per unit basis, general and administrative expenses remained flat at $0.10 per Mcfe for the years ended
December 31, 2013 and 2012 as a result of decreased production volumes during 2013.

Other Income and Expenses:

Interest Expense.

Interest expense increased to $101.5 million during the period ended December 31, 2013
compared to $88.2 million during the same period in 2012 primarily as a result of higher average borrowings
outstanding during the year ended December 31, 2013 and lower amounts of capitalized interest related to
unevaluated oil and gas properties that are excluded from amortization. For the years ended December 31, 2013
and 2012, the Company capitalized $2.0 million and $15.0 million, respectively, in interest associated with
unevaluated oil and gas properties that are excluded from amortization and actively being evaluated as well as
work in process relating to gathering systems that are not currently in service.

Other Expenses. During the year ended December 31, 2012,

the Company recognized contract
cancellation expenses of $15.5 million. In response to low natural gas prices, the Company reduced its drilling
rig count to two operated rigs during 2012.

Deferred Gain on Sale of Liquids Gathering System. During the year ended December 31, 2013, the
Company recognized $10.6 million in deferred gain on sale of the liquids gathering system relating to the sale of
a system of pipelines and central gathering facilities and certain associated real property rights in the Pinedale
Anticline in Wyoming during December 2012. The net proceeds received for the assets were $224.2 million.

Commodity Derivatives:

Gain (Loss) on Commodity Derivatives. During the year ended December 31, 2013, the Company
recognized a loss of $46.8 million compared with a gain of $73.6 million related to commodity derivatives
during the year ended December 31, 2012. Of this total, the Company recognized $20.9 million related to
realized loss on commodity derivatives as compared to $304.0 million related to realized gain during the year
ended December 31, 2012. The realized gain or loss on commodity derivatives relates to actual amounts received
or paid under the Company’s derivative contracts. This gain or loss on commodity derivatives also includes a
$25.9 million unrealized loss on commodity derivatives at December 31, 2013 as compared to a $230.4 million
unrealized loss on commodity derivatives at December 31, 2012. The unrealized gain or loss on commodity
derivatives represents the non-cash charge attributable to the change in the fair value of these derivative
instruments.

Income (Loss) from Continuing Operations:

Pretax Income (Loss). The Company recognized income before income taxes of $234.2 million for the
year ended December 31, 2013 compared with loss before income taxes of $2.9 billion for the same period in
2012. The increase in earnings is primarily related to the non-cash ceiling test and other impairments during
2012, decreased DD&A expense in 2013 as a result of a lower depletable base, and higher natural gas prices
partially offset by lower realized gains on commodity derivatives and decreased production during 2013.

Income Taxes. As a result of the tax effect of the non-cash ceiling test and other impairments, the
Company’s previously recorded net deferred tax liability fully reversed into a net deferred tax asset during the
quarter ended June 30, 2012. The Company has recorded a full valuation allowance against its net deferred tax
asset balance of $363.4 million as of December 31, 2013. This valuation allowance may be reversed in future
periods against future taxable income. The income tax benefit recognized for the year ended December 31, 2013
was $3.6 million compared with an income tax benefit of $700.2 million for the year ended December 31, 2012.

46

Net Income (Loss). For the year ended December 31, 2013, the Company recognized net income of
$237.8 million or $1.54 per diluted share as compared with net loss of $2.2 billion or ($14.24) per diluted share
for the same period in 2012. The increase in earnings is primarily related to the non-cash ceiling test and other
impairments during 2012, decreased DD&A expense in 2013 as a result of a lower depletable base, and higher
natural gas prices partially offset by lower realized gains on commodity derivatives and decreased production
during 2013.

Results of Operations — Year Ended December 31, 2012 vs. Year Ended December 31, 2011

During the year ended December 31, 2012, production increased on a gas equivalent basis to 257.0 Bcfe
from 245.3 Bcfe for the same period in 2011 as a result of wells put on production in 2012. Realized natural gas
prices, including realized gain and loss on commodity derivatives, decreased to $4.01 per Mcf during the year
ended December 31, 2012 as compared to $5.05 per Mcf during 2011. During the year ended December 31,
2012, the Company’s average price for natural gas was $2.79 per Mcf, excluding realized gains and losses on
commodity derivatives as compared to $4.15 per Mcf for the same period in 2011. The decrease in average
natural gas prices largely contributed to a 26% decrease in revenues for the year ended December 31, 2012 to
$810.0 million as compared to $1.1 billion in 2011.

LOE increased to $64.5 million for the year ended December 31, 2012 compared to $51.8 million during the
same period in 2011 primarily due to increased well counts resulting from the Company’s drilling program. On a
unit of production basis, LOE costs increased to $0.25 per Mcfe at December 31, 2012 compared to $0.21 per
Mcfe at December 31, 2011 as a result of higher lease operating expense on non-operated wells in Pennsylvania.

During the year ended December 31, 2012, production taxes were $60.8 million compared to $97.1 million
during the same period in 2011, or $0.24 per Mcfe, compared to $0.40 per Mcfe. Production taxes are primarily
calculated based on a percentage of revenue from production in Wyoming after certain deductions and were 7.5%
of revenues for the year ended 2012 and 8.8% for the same period in 2011. In addition, the year ended
December 31, 2012 includes charges related to Pennsylvania impact fees totaling $5.6 million while the period
ended December 31, 2011 did not include any charges related to impact fees in Pennsylvania. The decrease in per
unit taxes is primarily attributable to decreased sales revenues as a result of decreased natural gas prices,
excluding the effects of commodity derivatives, during the year December 31, 2012 as compared to the same
period in 2011.

Gathering fees increased to $59.0 million for the year ended December 31, 2012 compared to $56.5 million
during the same period in 2011 largely due to increased production volumes. On a per unit basis, gathering fees
remained flat at $0.23 per Mcfe for the year ended December 31, 2012 and 2011.

The Company incurred firm transportation charges totaling $84.5 million for the period ended December 31,
2012 as compared to $64.2 million for the same period in 2011 in association with REX pipeline charges. On a
per unit basis, transportation charges increased to $0.33 per Mcfe (on total company volumes) for the period
ended December 31, 2012 as compared to $0.26 for the same period in 2011 primarily due to demand charges
associated with the additional capacity of 50 MMMBtu per day secured on the REX pipeline system beginning in
January 2012.

DD&A expenses increased to $389.0 million during the period ended December 31, 2012 from
$346.4 million for the same period in 2011, attributable primarily to increased production volumes and a higher
depletion rate. On a unit of production basis, DD&A increased to $1.51 per Mcfe at December 31, 2012 from
$1.41 at December 31, 2011 primarily as a result of increased costs in Pennsylvania.

The Company recorded a $2.9 billion non-cash write-down of the carrying value of its proved oil and
natural gas properties for the period ended December 31, 2012 as a result of ceiling test limitations, which is
reflected as ceiling test and other impairments in the accompanying Consolidated Statements of Operations. The
ceiling test was calculated based upon the average of quoted market prices in effect on the first day of the month

47

for the preceding twelve month period at December 31, 2012, September 30, 2012 and June 30, 2012 of $2.76
per MMBtu, $2.83 per MMBtu and $3.15 per MMBtu for Henry Hub natural gas, respectively, and $94.71 per
barrel, $94.97 per barrel and $95.67 per barrel for West Texas Intermediate oil, respectively, adjusted for market
differentials. The write-down reduced earnings in the period and will result in a lower DD&A rate in future
periods. The Company did not have any write-downs related to the full cost ceiling limitation during the prior
year period ended December 31, 2011. See Note 1(e). In addition, the Company recognized impairments of $92.5
million during the year ended December 31, 2012 related to the decline in fair value as defined in FASB ASC
820 as a result of forecast decreased throughput volumes on its gathering facilities in Pennsylvania due to the
decline in commodity prices. These assets are included in Property, Plant and Equipment in the Consolidated
Balance Sheets. (See Note 8 for additional information on fair value).

General and administrative expenses decreased slightly to $25.1 million for the period ended December 31,
2012 compared to $26.0 million for the same period in 2011. On a per unit basis, general and administrative
expenses decreased to $0.10 per Mcfe for the year ended December 31, 2012 compared with $0.11 per Mcfe in
2011 as a result of increased production volumes during 2012.

Interest expense increased to $88.2 million during the period ended December 31, 2012 compared to
$63.2 million during the same period in 2011 primarily as a result of higher average borrowings outstanding
during the year ended December 31, 2012 and lower amounts of capitalized interest related to unevaluated oil
and gas properties that are excluded from amortization. For the years ended December 31, 2012 and 2011, the
Company capitalized $15.0 million and $30.7 million, respectively, in interest associated with unevaluated oil
and gas properties that are excluded from amortization and actively being evaluated as well as work in process
relating to gathering systems that are not currently in service. At December 31, 2012, all costs related to
unevaluated properties that were previously excluded from capitalized costs being amortized have been impaired
and transferred to the capitalized costs being amortized in the full cost pool.

During the year ended December 31, 2012, the Company recognized contract cancellation expenses of $15.5
million. In response to low natural gas prices, the Company reduced its drilling rig count to two operated rigs,
down from six at December 31, 2011.

During the year ended December 31, 2012, the Company recognized $304.0 million related to realized gain
on commodity derivatives as compared to $213.3 million during the year ended December 31, 2011. The realized
gain or loss on commodity derivatives relates to actual amounts received or paid under the Company’s derivative
contracts.

At December 31, 2012, the Company recognized $230.4 million related to unrealized loss on commodity
derivatives as compared to $100.4 million related to unrealized gain on commodity derivatives at December 31,
2011. The unrealized gain or loss on commodity derivatives represents the non-cash change in the fair value of
these derivative instruments.

The Company recognized a loss before income taxes of $2.9 billion for the year ended December 31, 2012
compared with income before income taxes of $710.9 million for the same period in 2011. The decrease in
earnings is primarily related to the non-cash ceiling test and other impairments and decreased natural gas prices
partially offset by increased production during 2012.

As a result of the tax effect of the non-cash ceiling test and other impairments, the Company’s previously
recorded net deferred tax liability fully reversed into a net deferred tax asset during the quarter ended June 30,
2012. The Company has recorded a full valuation allowance against its net deferred tax asset balance of $449.8
million as of December 31, 2012. This valuation allowance may be reversed in future periods against future
taxable income. The income tax benefit recognized for the year ended December 31, 2012 was $700.2 million
compared with an income tax provision of $257.7 million for the year ended December 31, 2011.

48

For the year ended December 31, 2012, the Company recognized net loss of $2.2 billion or ($14.24) per
diluted share as compared with net income of $453.2 million or $2.94 per diluted share for the same period in
2011. The decrease in earnings is primarily related to the non-cash ceiling test and other impairments and
decreased natural gas prices partially offset by increased production during 2012.

The discussion and analysis of the Company’s financial condition and results of operations is based upon
consolidated financial statements, which have been prepared in accordance with U.S. GAAP. In addition,
application of generally accepted accounting principles requires the use of estimates, judgments and assumptions
that affect the reported amounts of assets and liabilities as of the date of the financial statements as well as the
revenues and expenses reported during the period. Changes in these estimates, judgments and assumptions will
occur as a result of future events, and, accordingly, actual results could differ from amounts estimated.

LIQUIDITY AND CAPITAL RESOURCES

During the year ended December 31, 2013, the Company relied on cash provided by operations along with
borrowings under the Credit Agreement (defined below) to finance its capital expenditures. In addition, the
Company completed the issuance of $450.0 million of senior notes in December 2013 to finance a portion of the
purchase price of the Uinta Basin acquisition (See Note 5). The Company participated in 152 wells that were
drilled to total depth and cased during 2013. For the year ended December 31, 2013, capital expenditures,
excluding the Uinta Basin acquisition of $649.8 million, were $377.0 million ($370.7 million related to oil and
gas exploration and development expenditures, $5.5 million related to gathering system expenditures and $0.8
million related to other property costs).

At December 31, 2013, the Company reported a cash position of $10.7 million compared to $12.9 million at
December 31, 2012. Working capital deficit at December 31, 2013 was $278.8 million compared to a deficit of
$388.2 million at December 31, 2012. At December 31, 2013, the Company had $460.0 million in outstanding
borrowings and $540.0 million of available borrowing capacity under the Credit Agreement (defined below). In
addition, the Company had $2.0 billion outstanding in senior notes (See Note 5). Other long-term obligations of
$91.9 million at December 31, 2013 is comprised of items payable in more than one year, primarily related to
production taxes and asset retirement obligations.

The Company’s positive cash provided by operating activities, along with availability under the senior
credit facility, are projected to be sufficient to fund the Company’s budgeted capital investment program for
2014, which is currently projected to be approximately $560.0 million. Of the $560.0 million budget, the
Company plans to allocate approximately 92% to exploration and development related expenditures and the
remainder to gathering and infrastructure and other.

Bank indebtedness. The Company (through its subsidiary, Ultra Resources, Inc.) is a party to a senior
revolving credit facility with a syndicate of banks led by JP Morgan Chase Bank, N.A. (the “Credit Agreement”).
The Credit Agreement provides an initial loan commitment of $1.0 billion, which may be increased up to $1.25
billion at the request of the borrower and with the consent of lenders who are willing to increase their loan
commitments, provides for the issuance of letters of credit of up to $250.0 million in aggregate, and matures in
October 2016. With the majority (over 50%) lender consent, the term of the consenting lenders’ commitments
may be extended for up to two successive one-year periods at the Borrower’s request. At December 31, 2013, the
Company had $460.0 million in outstanding borrowings and $540.0 million of available borrowing capacity
under the Credit Agreement.

Loans under the Credit Agreement are unsecured and bear interest, at the Borrower’s option, based on (A) a
rate per annum equal to the prime rate or the weighted average fed funds rate on overnight transactions during
the preceding business day plus a margin based on a grid of Ultra Resources, Inc.’s consolidated leverage ratio
(125 basis points as of December 31, 2013) or (B) a base Eurodollar rate, substantially equal to the LIBOR rate,
plus a margin based on a grid of the Borrower’s consolidated leverage ratio (225 basis points per annum as of
December 31, 2013). The Company also pays commitment fees on the unused commitment under the facility
based on a grid of its consolidated leverage ratio.

49

The Credit Agreement contains typical and customary representations, warranties, covenants and events of
default. The Credit Agreement includes restrictive covenants requiring the Borrower to maintain a consolidated
leverage ratio of no greater than three and one half times to one and, as long as Ultra Resources, Inc.’s debt rating
is below investment grade, the maintenance of an annual ratio of the net present value of Ultra Resources, Inc.’s
oil and gas properties to total funded debt of no less than one and one half times to one. At December 31, 2013,
the Company was in compliance with all of its debt covenants under the Credit Agreement. (See Note 5).

Ultra Resources, Inc. Senior Notes: The Company’s subsidiary, Ultra Resources, Inc., has outstanding
Senior Notes rank pari passu with the Company’s Credit Agreement. Payment of the Senior Notes is guaranteed
by Ultra Petroleum Corp. and UP Energy Corporation. The Senior Notes are pre-payable in whole or in part at
any time and are subject to representations, warranties, covenants and events of default customary for a senior
note financing. At December 31, 2013, the Company was in compliance with all of its debt covenants under the
Senior Notes. (See Note 5).

Ultra Petroleum Corp. Senior Notes: On December 12, 2013, the Company issued $450.0 million of
5.75% Senior Notes due 2018 (“Notes”). The Notes are general, unsecured senior obligations of the Company
and mature on December 15, 2018. The Notes rank equally in right of payment to all existing and future senior
indebtedness of the Company and effectively rank junior to all future secured indebtedness of the Company (to
the extent of the value of the collateral securing such indebtedness). The Notes are not guaranteed by the
Company’s subsidiaries and so are structurally subordinated to the indebtedness and other obligations of the
Company’s subsidiaries. On and after December 15, 2015, the Company may redeem all or, from time to time, a
part of the Notes at the following prices expressed as a percentage of principal amount of the Notes: (2015 —
102.875%; 2016 — 101.438%; and 2017 and thereafter — 100.000%). The Notes are subject to covenants that
restrict the Company’s ability to incur indebtedness, make distributions and other restricted payments, grant
liens, use the proceeds of asset sales, make investments and engage in affiliate transactions. In addition, the
Notes contain events of default customary for a senior note financing. At December 31, 2013, the Company was
in compliance with all of its debt covenants under the Notes. (See Note 5).

Operating Activities. During the year ended December 31, 2013, net cash provided by operating activities
was $472.6 million, a 28% decrease from $654.8 million for the same period in 2012. The decrease in net cash
provided by operating activities was largely attributable to decreased realized prices, including realized gains and
losses on commodity derivatives, and decreased production during the year ended December 31, 2013 as
compared to the same period in 2012.

Investing Activities. During the year ended December 31, 2013, net cash used in investing activities was
$1.1 billion as compared to $577.2 million for the same period in 2012. The increase in net cash used in investing
activities is largely related to acquisition costs of $649.8 million associated with the Uinta Basin acquisition and
proceeds from the sale of the LGS during December 2012. This increase is partially offset by decreased capital
investments associated with the Company’s drilling activities in 2013 as compared to 2012.

Financing Activities. During the year ended December 31, 2013, net cash provided by financing activities
was $618.6 million as compared to net cash used in financing activities of $76.0 million for the same period in
2012. The change in cash provided by net financing activities is primarily due to increased borrowings during
2013 as compared to 2012, primarily related to the Uinta Basin acquisition.

Outlook

We believe we are well positioned for the current economic environment because of our status as a low cost
operator in the industry combined with our financial flexibility. In 2013, we maintained our low cost structure
which contributes to our long-term favorable returns and growth profile.

Although our net cash provided by operating activities was negatively affected by reduced natural gas
prices, we believe that we will continue to generate positive cash flow from operations, which, along with our

50

available cash, will provide sufficient liquidity to fund our capital investments and operations over the next
twelve months. We continue to monitor and evaluate the impact of reduced commodity prices in order to
determine the appropriate size and nature of our capital investment program.

We expect to rely on our available cash, our existing credit facility and the cash generated from operations
to meet our obligations. While we continue to monitor the overall health of the credit markets, a renewed, long-
term disruption in the credit markets could make financing more expensive or unavailable, which could have a
material adverse effect on our operations.

OFF BALANCE SHEET ARRANGEMENTS

The Company did not have any off-balance sheet arrangements as of December 31, 2013.

(1) The Company’s average net interest in payments related to REX transportation charges is approximately

80%.

Transportation contract. The Company is an anchor shipper on REX securing pipeline infrastructure
providing sufficient capacity to transport a portion of its natural gas production away from its properties and to
provide for reasonable basis differentials for its natural gas in the future. REX begins at the Opal Processing
Plant in southwest Wyoming and traverses Wyoming and several other states to an ultimate terminus in eastern
Ohio. The Company’s commitment involves a capacity of 200 MMMBtu per day of natural gas for a term of
10 years commencing in November 2009. During the first quarter of 2009, the Company entered into agreements
to secure an additional capacity of 50 MMMBtu per day on the REX pipeline system, beginning in January 2012
through December 2018. The Company is obligated to pay REX certain demand charges related to its rights to
hold this firm transportation capacity as an anchor shipper. The Company has the right, but not the obligation, to
deliver its natural gas production into the REX pipeline, but must pay its reservation charges in either event. The
Company continuously assesses its best available market options when determining the appropriate level of
utilization of its REX capacity.

Operating lease. During December 2012, the Company sold its system of pipelines and central gathering
facilities (the “LGS”) and certain associated real property rights in the Pinedale Anticline in Wyoming and
entered into a long-term, triple net lease agreement (the “Lease Agreement”) relating to the use of the LGS. The
Lease Agreement provides for an initial term of 15 years and potential successive renewal terms of 5 years or
75% of the then remaining useful life of the LGS at the sole discretion of the Company. Annual rent for the
initial term under the Lease Agreement is $20.0 million (as adjusted annually for changes based on the consumer
price index, which is 1.53% at January 1, 2014) and may increase if certain volume thresholds are exceeded. The
lease is classified as an operating lease.

51

All of the Company’s lease obligations are related to leases that are classified as operating leases. These
leases contain certain provisions that could result in accelerated lease payments. The Company has considered
the effect of these provisions on minimum lease payments in its lease classification analysis and has determined
that the default provisions do not impact classification of any the Company’s operating leases.

Drilling contracts. As of December 31, 2013, the Company had committed to drilling obligations that will
continue into 2016. The commitments expire in 2016 and were entered into to fulfill the Company’s drilling
program initiatives.

Office space lease. The Company maintains office space in Colorado, Texas, Wyoming and Pennsylvania
with total remaining commitments for office leases of $2.2 million at December 31, 2013 ($0.8 million in 2014;
$0.6 million in 2015 through 2016; $0.6 million in 2017 through 2018 and $0.2 million in 2019).

52

Item 7A. — Quantitative and Qualitative Disclosures About Market Risk

Objectives and Strategy: The Company’s major market risk exposure is in the pricing applicable to its
natural gas and oil production. Realized pricing is currently driven primarily by the prevailing price for the
Company’s Wyoming natural gas production. Historically, prices received for natural gas production have been
volatile and unpredictable. Pricing volatility is expected to continue. As a result of its hedging activities, the
Company may realize prices that are less than or greater than the spot prices that it would have received
otherwise.

The Company relies on various types of derivative instruments to manage its exposure to commodity price
risk and to provide a level of certainty in the Company’s forward cash flows supporting the Company’s capital
investment program.

The Company’s hedging policy limits the amounts of resources hedged to not more than 50% of its forecast

production without Board approval.

Fair Value of Commodity Derivatives: FASB ASC 815 requires that all derivatives be recognized on the
balance sheet as either an asset or liability and be measured at fair value. Changes in the derivative’s fair value
are recognized currently in earnings unless specific hedge accounting criteria are met. The Company does not
apply hedge accounting to any of its derivative instruments.

Derivative contracts that do not qualify for hedge accounting treatment are recorded as derivative assets and
liabilities at fair value on the balance sheet and the associated unrealized gains and losses are recorded as current
expense or income in the income statement. Unrealized gains or losses on commodity derivatives represent the
non-cash change in the fair value of these derivative instruments and do not impact operating cash flows on the
cash flow statement.

Commodity Derivative Contracts: At December 31, 2013,

the Company had the following open
commodity derivative contracts to manage price risk on a portion of its production whereby the Company
receives the fixed price and pays the variable price. The reference prices of these commodity derivative contracts
are typically referenced to an index prices as published by independent third parties.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company is responsible for the preparation and integrity of all information
contained in this Annual Report. The accompanying financial statements have been prepared in conformity with
accounting principles generally accepted in the United States of America. The financial statements include
amounts that are management’s best estimates and judgments.

Our management is responsible for establishing and maintaining adequate internal control over financial
reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the
participation of our management, including our chief executive officer and chief financial officer, we conducted
an evaluation of the effectiveness of our internal control over financial reporting based on the framework in
Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission (1992 framework). Based on our evaluation under the framework in Internal Control —
Integrated Framework, our management concluded that our internal control over financial reporting was effective
as of December 31, 2013.

The effectiveness of our internal control over financial reporting has been audited by Ernst & Young LLP,

an independent registered public accounting firm, as stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Ultra Petroleum Corp.

We have audited the accompanying consolidated balance sheets of Ultra Petroleum Corp. as of
December 31, 2013 and 2012, and the related consolidated statements of operations, shareholders’ equity, and
cash flows for each of the three years in the period ended December 31, 2013. These financial statements are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by management, as well as evaluating
the overall financial statement presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the
consolidated financial position of Ultra Petroleum Corp. at December 31, 2013 and 2012, and the consolidated
results of its operations and its cash flows for each of the three years in the period ended December 31, 2013, in
conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), Ultra Petroleum Corp.’s internal control over financial reporting as of December 31, 2013, based
on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (1992 framework) and our report dated February 25, 2014 expressed
an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of Ultra Petroleum Corp.

We have audited Ultra Petroleum Corp.’s internal control over financial reporting as of December 31, 2013,
based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (1992 framework) (the COSO criteria). Ultra Petroleum Corp.’s
management
is responsible for maintaining effective internal control over financial reporting, and for its
assessment of the effectiveness of internal control over financial reporting included in the accompanying
Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion
on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether effective internal control over financial reporting was maintained in all material respects. Our
audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a
material weakness exists, testing and evaluating the design and operating effectiveness of internal control based
on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We
believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the
company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

In our opinion, Ultra Petroleum Corp. maintained, in all material respects, effective internal control over

financial reporting as of December 31, 2013, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the consolidated balance sheets of Ultra Petroleum Corp. as of December 31, 2013 and 2012, and
the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the three years
in the period ended December 31, 2013 of Ultra Petroleum Corp. and our report dated February 25, 2014
expressed an unqualified opinion thereon.

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(All amounts in this Report on Form 10-K are expressed in thousands of U.S. dollars (except per share data),

unless otherwise noted).

Ultra Petroleum Corp. (the “Company”) is an independent oil and natural gas company engaged in the
acquisition, exploration, development, and production of oil and natural gas properties. The Company is
incorporated under the laws of the Yukon Territory, Canada. The Company’s principal business activities are in
the Green River Basin of southwest Wyoming, the north-central Pennsylvania area of the Appalachian Basin and
in the Uinta Basin in northeast Utah.

1. SIGNIFICANT ACCOUNTING POLICIES:

(a) Basis of presentation and principles of consolidation: The consolidated financial statements include
the accounts of the Company and its wholly owned subsidiaries. The Company presents its financial statements
in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). All inter-company transactions
and balances have been eliminated upon consolidation.

(b) Cash and cash equivalents: The Company considers all highly liquid investments with an original

maturity of three months or less to be cash equivalents.

(c) Restricted cash: Restricted cash represents cash received by the Company from production sold where

the final division of ownership of the production is unknown or in dispute.

(d) Property, plant and equipment: Capital assets are recorded at cost and depreciated using the declining-
balance method based on a seven-year useful life. Gathering system expenditures are recorded at cost and
depreciated using the straight-line method based on a 30-year useful life. The gathering system assets, which are
downstream of the Company’s well pads, are depreciated separately from proven oil and gas properties because
they are expected to be used to transport oil and gas not currently included in the Company’s proved reserves,
including production expected from probable and possible reserves, as well as from third parties.

The Company recognized impairments of $92.5 million during the year ended December 31, 2012 related to
the decline in fair value as defined in FASB ASC 820 as a result of forecast decreased throughput volumes on its
gathering facilities in Pennsylvania due to the decline in commodity prices. These assets are included in Property,
Plant and Equipment in the Consolidated Balance Sheets.

(e) Oil and natural gas properties: The Company uses the full cost method of accounting for exploration
and development activities as defined by the Securities and Exchange Commission (“SEC”) Release No. 33-
8995, Modernization of Oil and Gas Reporting Requirements (“SEC Release No. 33-8995”) and Financial
Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 932, Extractive
Activities — Oil and Gas (“FASB ASC 932”). Separate cost centers are maintained for each country in which the
Company incurs costs. Under this method of accounting, the costs of unsuccessful, as well as successful,
exploration and development activities are capitalized as oil and gas properties. This includes any internal costs
that are directly related to exploration and development activities but does not include any costs related to
production, general corporate overhead or similar activities. The carrying amount of oil and natural gas
properties also includes estimated asset retirement costs recorded based on the fair value of the asset retirement
obligation when incurred. Gain or loss on the sale or other disposition of oil and natural gas properties is not
recognized, unless the gain or loss would significantly alter the relationship between capitalized costs and proved
reserves of oil and natural gas attributable to a country.

62

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The sum of net capitalized costs and estimated future development costs of oil and natural gas properties are
amortized using the units-of-production method based on the proved reserves as determined by independent
petroleum engineers. Oil and natural gas reserves and production are converted into equivalent units based on
relative energy content. Asset retirement obligations are included in the base costs for calculating depletion.

Under the full cost method, costs of unevaluated properties and major development projects expected to
require significant future costs may be excluded from capitalized costs being amortized. The Company excludes
significant costs until proved reserves are found or until it is determined that the costs are impaired. Excluded
costs, if any, are reviewed quarterly to determine if impairment has occurred. The amount of any impairment is
transferred to the capitalized costs being amortized.

Companies that use the full cost method of accounting for oil and natural gas exploration and development
activities are required to perform a ceiling test calculation each quarter. The full cost ceiling test is an impairment
test prescribed by SEC Regulation S-X Rule 4-10. The ceiling test is performed quarterly, on a country-by-
country basis, utilizing the average of prices in effect on the first day of the month for the preceding twelve
month period in accordance with SEC Release No. 33-8995. The ceiling limits such pooled costs to the aggregate
of the present value of future net revenues attributable to proved crude oil and natural gas reserves discounted at
10% plus the lower of cost or market value of unproved properties less any associated tax effects. If such
capitalized costs exceed the ceiling, the Company will record a write-down to the extent of such excess as a non-
cash charge to earnings. Any such write-down will reduce earnings in the period of occurrence and results in a
lower depletion, depreciation and amortization (“DD&A”) rate in future periods. A write-down may not be
reversed in future periods even though higher oil and natural gas prices may subsequently increase the ceiling.

During 2012, the Company recorded a $2.9 billion non-cash write-down of the carrying value of the
Company’s proved oil and gas properties as a result of ceiling test limitations, which is reflected within ceiling
test and other impairments in the accompanying Consolidated Statements of Operations. The ceiling test was
calculated based upon the average of quoted market prices in effect on the first day of the month for the
preceding twelve month period at December 31, 2012, September 30, 2012 and June 30, 2012 for Henry Hub
natural gas and West Texas Intermediate oil, adjusted for market differentials. The Company did not have any
write-downs related to the full cost ceiling limitation in 2013 or 2011.

(f) Inventories: At December 31, 2013, inventory of $5.2 million primarily includes the cost of pipe and
production equipment that will be utilized during the 2014 drilling program and crude oil inventory. Materials
and supplies inventories are carried at lower of cost or market and include expenditures and other charges
directly and indirectly incurred in bringing the inventory to its existing condition and location. Selling expenses
and general and administrative expenses are reported as period costs and excluded from inventory cost. The
Company uses the weighted average method of recording its materials and supplies inventory. Crude oil
inventory is valued at the Company’s average sales price for the respective month.

(g) Derivative instruments and hedging activities: The Company follows FASB ASC Topic 815,
Derivatives and Hedging (“FASB ASC 815”). The Company records the fair value of its commodity derivatives
as an asset or liability on the Consolidated Balance Sheets, and records the changes in the fair value of its
commodity derivatives in the Consolidated Statements of Operations as an unrealized gain or loss on commodity
derivatives. The Company does not offset the value of its derivative arrangements with the same counterparty.
(See Note 7).

(h) Income taxes:

Income taxes are accounted for under the asset and liability method. Deferred tax assets
and liabilities are recognized for the future tax consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and

63

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to
apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.
The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that
includes the enactment date. Valuation allowances are recorded related to deferred tax assets based on the “more
likely than not” criteria described in FASB ASC Topic 740, Income Taxes. In addition, the Company recognizes
the financial statement benefit of a tax position only after determining that the relevant tax authority would more
likely than not sustain the position following an audit.

As a result of the tax effect of the ceiling test and other impairments recorded during the year ended
December 31, 2012, the Company’s previously recorded net deferred tax liability fully reversed into a net
deferred tax asset. The Company has recorded a full valuation allowance against its net deferred tax asset balance
of $363.4 million as of December 31, 2013. This valuation allowance may be reversed in future periods against
future income.

(i) Earnings per share: Basic (loss) earnings per share is computed by dividing net (loss) earnings
attributable to common stockholders by the weighted average number of common shares outstanding during each
period. Diluted (loss) earnings per share is computed by adjusting the average number of common shares
outstanding for the dilutive effect, if any, of common stock equivalents. The Company uses the treasury stock
method to determine the dilutive effect.

common share:

(1) Due to the net loss for the year ended December 31, 2012, 1.9 million shares for options and restricted stock

units were anti-dilutive and excluded from the computation of loss per share.

(j) Use of estimates: Preparation of consolidated financial statements in accordance with U.S. GAAP
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities,
the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts
of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(k) Accounting for share-based compensation: The Company measures and recognizes compensation
expense for all share-based payment awards made to employees and directors, including employee stock options,
based on estimated fair values in accordance with FASB ASC Topic 718, Compensation — Stock Compensation.

64

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

(l) Fair value accounting: The Company follows FASB ASC Topic 820, Fair Value Measurements and
Disclosures (“FASB ASC 820”), which defines fair value, establishes a framework for measuring fair value
under GAAP, and expands disclosures about fair value measurements. This statement applies under other
accounting topics that require or permit fair value measurements. See Note 8 for additional information.

(m) Asset retirement obligation: The initial estimated retirement obligation of properties is recognized as a
liability with an associated increase in oil and gas properties for the asset retirement cost. Accretion expense is
recognized over the estimated productive life of the related assets. If the fair value of the estimated asset
retirement obligation changes, an adjustment is recorded to both the asset retirement obligation and the asset
retirement cost. Revisions in estimated liabilities can result from revisions of estimated inflation rates, changes in
service and equipment costs and changes in the estimated timing of settling asset retirement obligations. As a full
cost company, settlements for asset retirement obligations for abandonment are adjusted to the full cost pool. The
asset retirement obligation is included within other long-term obligations in the accompanying Consolidated
Balance Sheets.

(n) Revenue recognition: The Company generally sells natural gas and condensate under both long-term
and short-term agreements at prevailing market prices and under multi-year contracts that provide for a fixed
price of oil and natural gas. The Company recognizes revenues when the oil and natural gas is delivered, which
occurs when the customer has taken title and has assumed the risks and rewards of ownership, prices are fixed or
determinable and collectability is reasonably assured. The Company accounts for oil and natural gas sales using
the “entitlements method.” Under the entitlements method, revenue is recorded based upon the Company’s
ownership share of volumes sold, regardless of whether it has taken its ownership share of such volumes. The
Company records a receivable or a liability to the extent it receives less or more than its share of the volumes and
related revenue. Any amount received in excess of the Company’s share is treated as a liability. If the Company
receives less than its entitled share, the underproduction is recorded as a receivable. At December 31, 2013 and
2012, the Company had a net natural gas imbalance liability of $3.3 million and $2.1 million, respectively.

Make-up provisions and ultimate settlements of volume imbalances are generally governed by agreements
between the Company and its partners with respect to specific properties or, in the absence of such agreements,
through negotiation. The value of volumes over- or under-produced can change based on changes in commodity
prices. The Company prefers the entitlements method of accounting for oil and natural gas sales because it allows
for recognition of revenue based on its actual share of jointly owned production, results in better matching of
revenue with related operating expenses, and provides balance sheet recognition of the estimated value of
product imbalances.

(o) Capitalized interest:

Interest is capitalized on the cost of unevaluated gas and oil properties that are
excluded from amortization and actively being evaluated, if any, as well as on work in process relating to
gathering systems that are not currently in service.

(p) Capital cost accrual: The Company accrues for exploration and development costs in the period

incurred, while payment may occur in a subsequent period.

(q) Reclassifications: Certain amounts in the financial statements of prior periods have been reclassified to

conform to the current period financial statement presentation.

(r) Recent accounting pronouncements:

In January 2013, the FASB issued Accounting Standards Update
No. 2013-01, Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and
Liabilities (“Update 2013-01”), which finalizes Proposed ASU No. 2012-250 and clarifies the scope of
transactions that are subject to disclosures concerning offsetting. Update 2013-01 addresses implementation

65

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

issues regarding the scope of ASU No. 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets
and Liabilities, issued in December 2011. Update 2013-01 clarifies that the scope of the disclosures under U.S.
GAAP is limited to derivatives, repurchase agreements and reverse purchase agreements, and securities
borrowing and securities lending transactions that are offset either in accordance with FASB ASC Section 210-
20-45, Balance Sheet — Offsetting — Other Presentation Matters, or FASB ASC Section 815-10-45, Derivatives
and Hedging — Overall — Other Presentation Matters, or are subject to a master netting arrangement or similar
agreement. Update 2013-01 requires an entity (1) to apply the amendments for annual reporting periods
beginning on or after January 1, 2013 and (2) to provide the required disclosures retrospectively for all
comparative periods presented. The implementation of the disclosure requirement did not have a material impact
on the Company’s consolidated results of operations, financial position or cash flows.

2. ASSET RETIREMENT OBLIGATIONS:

The Company is required to record the fair value of an asset retirement obligation as a liability in the period
in which it incurs a legal obligation associated with the retirement of tangible long-lived assets that result from
the acquisition, construction, development and/or normal use of the assets. The following table summarizes the
activities for the Company’s asset retirement obligations for the years ended:

the preceding twelve month period at December 31, 2012, September 30, 2012 and June 30, 2012 for Henry
Hub natural gas and West Texas Intermediate oil, adjusted for market differentials. The Company did not
have any write-downs related to the full cost ceiling limitation in 2013.
Interest is capitalized on the cost of unevaluated oil and natural gas properties that are excluded from
amortization and actively being evaluated as well as on work in process relating to gathering systems that
are not currently in service. For the years ended December 31, 2013 and 2012, total interest on outstanding
debt was $103.5 million and $103.2 million, respectively, of which $2.0 million and $15.0 million,
respectively, was capitalized on the cost of unevaluated oil and natural gas properties and work in process
relating to gathering systems that are not currently in service.

(3) On December 12, 2013 the Company, through its subsidiary, UPL Three Rivers Holdings, LLC, closed on the
acquisition of crude oil assets (the “Assets”) located in Three Rivers Field in Uintah County, Utah. The
acquisition leverages the Company’s technical expertise as the Uinta Basin has similar tight-sand geologic
characteristics to the Pinedale Field. The Assets were acquired at a contract price, prior to adjustments, of
$652.0 million from Axia Energy, LLC (“Axia”) and consist of producing wells, undeveloped acreage and
water and gas gathering assets. A purchase and sale agreement was executed between the parties on
October 18, 2013 with an effective date of October 1, 2013. The acquisition was financed through the issuance
of $450.0 million of senior notes (See Note 5) and the remainder under the Company’s credit facility.
The transaction was accounted for as a business combination and the net purchase price was allocated to oil
and gas properties ($640.6 million), acquired working capital ($4.5 million), gas and water gathering
systems ($4.7 million), oil inventory ($1.7 million) and asset retirement obligations ($1.7 million). Since
December 12, 2013, the Company has recognized $4.2 million and $3.4 million in revenues and revenues
less direct operating expenses, respectively, in the Consolidated Statements of Operations.
Had the Company owned the Assets for the year ended December 31, 2013, it would have recognized
unaudited pro forma revenues of $979.6 million and unaudited pro forma net earnings of $248.3 million.
Had the Company owned the Assets for the year ended December 31, 2012, it would have recognized
unaudited pro forma revenues of $814.6 million and an audited pro forma a net loss of $2.2 billion. The
unaudited pro forma consolidated results reflect pro forma adjustments to recognize the issuance of $450.0
million in senior notes (See Note 5) and the associated interest expense; interest expense associated with the
portion of debt incurred under the Company’s Credit Agreement to fund the purchase price; calculate the
estimated incremental depreciation, depletion and amortization expense, using the units of production
method, related to the purchase of the Assets and the accretion expense associated with the asset retirement
obligation. The unaudited pro forma consolidated results are not necessarily indicative of what
the
Company’s consolidated results of operations actually would have been had the business combination been
completed on January 1, 2012. In addition, the unaudited pro forma consolidated results do not purport to
project future results of operations of the combined company.

Unproven Properties

The Company holds interests in domestic projects in which costs related to these interests are not being
depleted pending determination of existence of estimated proved reserves. The Company will continue to assess
and allocate the unproven properties over the next several years as proved reserves are established and as
exploration dictates whether or not future areas will be developed.

(1) The Company recognized impairments of $92.5 million during the year ended December 31, 2012 related to
the decline in fair value as defined in FASB ASC 820 as a result of forecast decreased throughput volumes
on its gathering facilities in Pennsylvania due to the decline in commodity prices.

(2) During December 2012, the Company sold its system of pipelines and central gathering facilities (the
“LGS”) and certain associated real property rights in the Pinedale Anticline in Wyoming for net cash
proceeds of $203.0 million and additional consideration of $23.0 million in the form of marketable
securities which were sold during December 2012 for net cash proceeds of $21.2 million.

In Pennsylvania, the Company and its partners continue constructing gas gathering pipelines and facilities,
compression facilities and pipeline delivery stations to gather production from its newly completed natural gas
wells. These facilities are gathering systems and related infrastructure, and their construction is expected to
continue until the Company’s properties in Pennsylvania are fully developed. To date, none of the Company’s
natural gas production in Pennsylvania has required processing, treating or blending in order to remove natural
gas liquids or other impurities and it is anticipated that facilities of this type will not be required in the future to
accommodate the Company’s production.

Bank indebtedness. The Company (through its subsidiary, Ultra Resources, Inc.) is a party to a senior
revolving credit facility with a syndicate of banks led by JP Morgan Chase Bank, N.A. (the “Credit Agreement”).
The Credit Agreement provides an initial loan commitment of $1.0 billion, which may be increased up to $1.25
billion at the request of the borrower and with the consent of lenders who are willing to increase their loan

68

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

commitments, provides for the issuance of letters of credit of up to $250.0 million in aggregate, and matures in
October 2016. With the majority (over 50%) lender consent, the term of the consenting lenders’ commitments
may be extended for up to two successive one-year periods at the Borrower’s request. At December 31, 2013, the
Company had $460.0 million in outstanding borrowings and $540.0 million of available borrowing capacity
under the Credit Agreement.

Loans under the Credit Agreement are unsecured and bear interest, at the Borrower’s option, based on (A) a
rate per annum equal to the prime rate or the weighted average fed funds rate on overnight transactions during
the preceding business day plus a margin based on a grid of Ultra Resources, Inc.’s consolidated leverage ratio
(125 basis points as of December 31, 2013) or (B) a base Eurodollar rate, substantially equal to the LIBOR rate,
plus a margin based on a grid of the Borrower’s consolidated leverage ratio (225 basis points per annum as of
December 31, 2013). The Company also pays commitment fees on the unused commitment under the facility
based on a grid of its consolidated leverage ratio.

The Credit Agreement contains typical and customary representations, warranties, covenants and events of
default. The Credit Agreement includes restrictive covenants requiring the Borrower to maintain a consolidated
leverage ratio of no greater than three and one half times to one and, as long as the Company’s debt rating is
below investment grade, the maintenance of an annual ratio of the net present value of the Company’s oil and gas
properties to total funded debt of no less than one and one half times to one. At December 31, 2013, the
Company was in compliance with all of its debt covenants under the Credit Agreement.

Ultra Resources, Inc. Senior Notes: The Company’s Senior Notes rank pari passu with the Company’s
Credit Agreement. Payment of the Senior Notes is guaranteed by Ultra Petroleum Corp. and UP Energy
Corporation. The Senior Notes are pre-payable in whole or in part at any time and are subject to representations,
warranties, covenants and events of default customary for a senior note financing. At December 31, 2013, the
Company was in compliance with all of its debt covenants under the Senior Notes.

Ultra Petroleum Corp. Senior Notes: On December 12, 2013, the Company issued $450.0 million of
5.75% Senior Notes due 2018 (“Notes”). The Notes are general, unsecured senior obligations of the Company
and mature on December 15, 2018. The Notes rank equally in right of payment to all existing and future senior
indebtedness of the Company and effectively rank junior to all future secured indebtedness of the Company (to
the extent of the value of the collateral securing such indebtedness). The Notes are not guaranteed by the
Company’s subsidiaries and so are structurally subordinated to the indebtedness and other obligations of the
Company’s subsidiaries. On and after December 15, 2015, the Company may redeem all or, from time to time, a
part of the Notes at the following prices expressed as a percentage of principal amount of the Notes: (2015 —
102.875%; 2016 — 101.438%; and 2017 and thereafter — 100.000%). The Notes are subject to covenants that
restrict the Company’s ability to incur indebtedness, make distributions and other restricted payments, grant
liens, use the proceeds of asset sales, make investments and engage in affiliate transactions. In addition, the
Notes contain events of default customary for a senior note financing. At December 31, 2013, the Company was
in compliance with all of its debt covenants under the Notes.

Other long-term obligations: These costs primarily relate to the long-term portion of production taxes

payable and our asset retirement obligations.

6. SHARE BASED COMPENSATION:

The Company sponsors a share based compensation plan: the 2005 Stock Incentive Plan (the “2005 Plan”).
The plan is administered by the Compensation Committee of the Board of Directors (the “Committee”). The

69

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

share based compensation plan is an important component of the total compensation package offered to the
Company’s key service providers, and reflects the importance that the Company places on motivating and
rewarding superior results.

The 2005 Plan was adopted by the Company’s Board of Directors on January 1, 2005 and approved by the
Company’s shareholders on April 29, 2005. The purpose of the 2005 Plan is to foster and promote the long-term
financial success of the Company and to increase shareholder value by attracting, motivating and retaining key
employees, consultants, and outside directors, and providing such participants with a program for obtaining an
ownership interest in the Company that links and aligns their personal interests with those of the Company’s
shareholders, and thus, enabling such participants to share in the long-term growth and success of the Company.
To accomplish these goals, the 2005 Plan permits the granting of incentive stock options, non-statutory stock
options, stock appreciation rights, restricted stock, and other stock-based awards, some of which may require the
satisfaction of performance-based criteria in order to be payable to participants. The Committee determines the
terms and conditions of the awards, including, any vesting requirements and vesting restrictions or forfeitures
that may occur. The Committee may grant awards under the 2005 Plan until December 31, 2014, unless
terminated sooner by the Board of Directors.

The fair value of stock options that vested during the year ended December 31, 2011 was $9.8 million. As of
December 31, 2011, all options fully vested; therefore, no options vested during the years ended December 31,
2013 and 2012. The total intrinsic value of stock options exercised during the years ended December 31, 2013,
2012 and 2011 was immaterial, $0.3 million and $21.5 million, respectively.

At December 31, 2013, there was no unrecognized compensation cost related to non-vested, employee stock

options as all options fully vested as of December 31, 2011.

PERFORMANCE SHARE PLANS:

Long Term Incentive Plans. The Company offers a Long Term Incentive Plan (“LTIP”) in order to further
align the interests of key employees with shareholders and to give key employees the opportunity to share in the
long-term performance of the Company when specific corporate financial and operational goals are achieved.
Each LTIP covers a performance period of three years. In 2011, 2012 and 2013, the Compensation Committee
(the “Committee”) approved an award consisting of performance-based restricted stock units to be awarded to
each participant.

For each LTIP award,

the Committee establishes performance measures at

the beginning of each
performance period. Under each LTIP, the Committee establishes a percentage of base salary for each participant
which is multiplied by the participant’s base salary to derive a Long Term Incentive Value as a “target” value
which corresponds to the number of shares of the Company’s common stock the participant is eligible to receive
if the target level for all performance measures is met. In addition, each participant is assigned threshold and
maximum award levels in the event that actual performance is below or above target levels. For the 2011, 2012
and 2013 LTIP awards, the Committee established the following performance measures: return on equity, reserve
replacement ratio, and production growth.

For the year ended December 31, 2013, the Company recognized $6.9 million in pre-tax compensation
expense related to the 2011, 2012 and 2013 LTIP awards of restricted stock units. For the year ended
December 31, 2012, the Company recognized $7.9 million in pre-tax compensation expense related to the 2010,
2011 and 2012 LTIP awards of restricted stock units. For the year ended December 31, 2011, the Company
recognized $10.7 million in pre-tax compensation expense related to the 2009, 2010 and 2011 LTIP awards of
restricted stock units. The amounts recognized during the year ended December 31, 2013 assumes that target
performance objectives are attained for the 2011 LTIP and maximum performance objectives are attained under
the 2012 LTIP and 2013 LTIP plans. If the Company ultimately attains these performance objectives, the
associated total compensation, estimated at December 31, 2013, for each of the three year performance periods is
expected to be approximately $8.5 million, $12.7 million, and $15.5 million related to the 2011, 2012 and 2013
LTIP awards of restricted stock units, respectively. The 2010 LTIP Common Stock Award was paid in shares of
the Company’s stock to employees during the first quarter of 2013 and totaled $11.7 million (153,511 net
shares).

7. DERIVATIVE FINANCIAL INSTRUMENTS:

Objectives and Strategy: The Company’s major market risk exposure is in the pricing applicable to its
natural gas and oil production. Realized pricing is currently driven primarily by the prevailing price for the
Company’s Wyoming natural gas production. Historically, prices received for natural gas production have been
volatile and unpredictable. Pricing volatility is expected to continue. As a result of its hedging activities, the
Company may realize prices that are less than or greater than the spot prices that it would have received
otherwise.

72

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The Company relies on various types of derivative instruments to manage its exposure to commodity price
risk and to provide a level of certainty in the Company’s forward cash flows supporting the Company’s capital
investment program.

The Company’s hedging policy limits the amounts of resources hedged to not more than 50% of its forecast

production without Board approval.

Fair Value of Commodity Derivatives: FASB ASC 815 requires that all derivatives be recognized on the
balance sheet as either an asset or liability and be measured at fair value. Changes in the derivative’s fair value
are recognized currently in earnings unless specific hedge accounting criteria are met. The Company does not
apply hedge accounting to any of its derivative instruments.

Derivative contracts that do not qualify for hedge accounting treatment are recorded as derivative assets and
liabilities at fair value on the balance sheet and the associated unrealized gains and losses are recorded as current
expense or income in the income statement. Unrealized gains or losses on commodity derivatives represent the
non-cash change in the fair value of these derivative instruments and do not impact operating cash flows on the
cash flow statement.

Commodity Derivative Contracts: At December 31, 2013,

the Company had the following open
commodity derivative contracts to manage price risk on a portion of its production whereby the Company
receives the fixed price and pays the variable price. The reference prices of these commodity derivative contracts
are typically referenced to an index prices as published by independent third parties.

8. FAIR VALUE MEASUREMENTS:

As required by FASB ASC Topic 820, Fair Value Measurements and Disclosures (“FASB ASC 820”), the
Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an
orderly transaction between market participants at the measurement date and establishes a three level hierarchy
for measuring fair value. Fair value measurements are classified and disclosed in one of the following categories:

Level 1: Quoted prices (unadjusted) in active markets for identical assets and liabilities that we have

the ability to access at the measurement date.

Level 2: Inputs other than quoted prices included within Level 1 that are either directly or indirectly
observable for the asset or liability, including quoted prices for similar assets or liabilities in active markets,
quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices
that are observable for the asset or liability, and inputs that are derived from observable market data by
correlation or other means. Instruments categorized in Level 2 include non-exchange traded derivatives such
as over-the-counter forwards and swaps.

Level 3: Unobservable inputs for the asset or liability, including situations where there is little, if any,

market activity for the asset or liability.

The valuation assumptions the Company has used to measure the fair value of its commodity derivatives
were observable inputs based on market data obtained from independent sources and are considered Level 2
inputs (quoted prices for similar assets, liabilities (adjusted) and market-corroborated inputs).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In consideration of counterparty credit risk,

the Company assessed the possibility of whether each
counterparty to the derivative would default by failing to make any contractually required payments as scheduled
in the derivative instrument in determining the fair value. Additionally, the Company considers that it is of
substantial credit quality and has the financial resources and willingness to meet its potential repayment
obligations associated with the derivative transactions.

Fair Value of Long-Lived Assets

The Company recognized impairments of $92.5 million during the year ended December 31, 2012 related to
the decline in fair value as defined in FASB ASC 820 as a result of forecast decreased throughput volumes on its
gathering facilities in Pennsylvania due to the decline in commodity prices. These facilities are included in
Property, Plant and Equipment in the Consolidated Balance Sheets and were impaired to a fair value of $82.6
million based on the income approach, estimated using Level 3 fair value inputs.

Fair Value of Financial Instruments

The estimated fair value of financial instruments is the amount at which the instrument could be exchanged
currently between willing parties. The carrying amounts reported in the Consolidated Balance Sheets for cash
and cash equivalents, accounts receivable, and accounts payable approximate fair value due to the immediate or
short-term maturity of these financial instruments. The carrying amount of floating-rate debt approximates fair
value because the interest rates are variable and reflective of market rates. We use available market data and
valuation methodologies to estimate the fair value of our fixed rate debt. The inputs utilized to estimate the fair
value of the Company’s fixed rate debt are considered Level 2 fair value inputs. This disclosure is presented in
accordance with FASB ASC Topic 825, Financial Instruments, and does not impact our financial position, results
of operations or cash flows.

In assessing the realizability of the deferred tax assets, management considers whether it is more likely than
not that some or all of the deferred tax assets will not be realized. The ultimate realization of the deferred tax
assets is dependent upon the generation of future taxable income during the periods in which the temporary
differences become deductible. Among other items, management considers the scheduled reversal of deferred tax
liabilities, historical taxable income, projected future taxable income, and available tax planning strategies.

As a result of the ceiling test and other impairments recorded during the year ended December 31, 2012, the
Company’s previously recorded net deferred tax liability fully reversed into a net deferred tax asset. At
December 31, 2013 and 2012, the Company recorded a full valuation allowance against its net deferred tax asset
balance of $363.4 million and $449.8 million, respectively. Some or all of this valuation allowance may be
reversed in future periods against future income. The Company’s valuation allowance changed by $86.4 million
from December 31, 2012 to December 31, 2013. Of this amount, $81.9 million reduced the Company’s current
year deferred tax expense, and $4.5 million was reflected through shareholders’ equity.

As of December 31, 2013, the Company had approximately $14.1 million of U.S. federal alternative
minimum tax (AMT) credits available to offset regular U.S. Federal income taxes. These AMT credits do not

77

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

expire and can be carried forward indefinitely. The Company has $0.5 million of general business credits
available to offset U.S. federal income taxes. These general business credits expire in 2032. In addition, the
Company has $1.7 million of foreign tax credit carryforwards, none of which expire prior to 2017.

The Company generated a U.S. federal tax loss of $262.4 million for the year ended December 31, 2013. Of
this loss, $58.0 million was carried back to offset taxable income generated in prior tax years. An income tax
receivable of $8.0 million has been recorded at December 31, 2013 and is reflected as a reduction in current year
income tax expense in the Consolidated Statements of Operations. The remaining U.S. federal tax net operating
loss of $204.4 million will be carried forward to offset taxable income generated in future years, and if
unutilized, will expire in 2033. The Company has Pennsylvania state tax net operating loss carry forwards of
$545.1 million which will expire between 2031 and 2033. The Company has immaterial state tax net operating
loss carry forwards in other jurisdictions, none of which expire prior to 2020.

The Company did not have any unrecognized tax benefits and there was no effect on our financial condition
or results of operations related to accounting for uncertain tax positions. The amount of unrecognized tax benefits
did not change as of December 31, 2013.

Estimated interest and penalties related to potential underpayment on any unrecognized tax benefits are
classified as a component of tax expense in the Consolidated Statements of Operations. The Company has not
incurred any interest or penalties associated with unrecognized tax benefits.

The Company files a consolidated federal income tax return in the United States federal jurisdiction and
various combined, consolidated, unitary, and separate filings in several states, and international jurisdictions. The
income tax year 2010 has been audited by the Internal Revenue Service resulting in no material changes to the
Company’s taxes. With certain exceptions, including previous audited tax years, the income tax years 2010
through 2013 remain open to examination by the major taxing jurisdictions in which the Company has business
activity.

The undistributed earnings of the Company’s U.S. subsidiaries are considered to be indefinitely invested
outside of Canada. Accordingly, no provision for Canadian income taxes and/or withholding taxes has been
provided thereon.

10. EMPLOYEE BENEFITS:

The Company sponsors a qualified,

tax-deferred savings plan in accordance with provisions of
Section 401(k) of the Internal Revenue Code for its employees. Employees may defer 100% of their
compensation, subject to limitations. The Company matches all of the employee’s contribution up to 5% of
compensation, as defined by the plan, along with an employer discretionary contribution of 8%. The expense
associated with the Company’s contribution was $1.6 million, $1.8 million and $1.4 million for the years ended
December 31, 2013, 2012 and 2011, respectively.

11. COMMITMENTS AND CONTINGENCIES:

Transportation contract. The Company is an anchor shipper on REX securing pipeline infrastructure
providing sufficient capacity to transport a portion of its natural gas production away from southwest Wyoming
and to provide for reasonable basis differentials for its natural gas in the future. REX begins at the Opal
Processing Plant in southwest Wyoming and traverses Wyoming and several other states to an ultimate terminus
in eastern Ohio. The Company’s commitment involves a capacity of 200 MMMBtu per day of natural gas
through November 2019, and the Company is obligated to pay REX certain demand charges related to its rights
to hold this firm transportation capacity as an anchor shipper.

78

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Subsequently, the Company entered into agreements to secure an additional capacity of 50 MMMBtu per
day on the REX pipeline system, beginning in January 2012 through December 2018. This additional capacity
provides the Company with the ability to move additional volumes from its producing wells in Wyoming to
markets in the eastern U.S.

The Company currently projects that demand charges related to the remaining term of the contract will total

approximately $569.7 million.

Operating lease. During December 2012, the Company sold its system of pipelines and central gathering
facilities (the “LGS”) and certain associated real property rights in the Pinedale Anticline in Wyoming and
entered into a long-term, triple net lease agreement (the “Lease Agreement”) relating to the use of the LGS. The
Lease Agreement provides for an initial term of 15 years and potential successive renewal terms of 5 years or
75% of the then remaining useful life of the LGS at the sole discretion of the Company. Annual rent for the
initial term under the Lease Agreement is $20.0 million (as adjusted annually for changes based on the consumer
price index) and may increase if certain volume thresholds are exceeded. The lease is classified as an operating
lease. The Company currently projects that
total
approximately $283.8 million.

lease payments related to the Lease Agreement will

All of the Company’s lease obligations are related to leases that are classified as operating leases. These
leases contain certain provisions that could result in accelerated lease payments. The Company has considered
the effect of these provisions on minimum lease payments in its lease classification analysis and has determined
that the default provisions do not impact classification of any the Company’s operating leases.

Drilling contracts. As of December 31, 2013, the Company had committed to drilling obligations totaling
$56.5 million ($35.9 million due in 2014, $20.6 million due in 2015 through 2016). The commitments expire in
2016 and were entered into to fulfill the Company’s drilling program initiatives.

Office space lease. The Company maintains office space in Colorado, Texas, Wyoming and Pennsylvania
with total remaining commitments for office leases of $2.2 million at December 31, 2013 ($0.8 million in 2014;
$0.6 million in 2015 through 2016; $0.6 million in 2017 through 2018 and $0.2 million in 2019).

During the years ended December 31, 2013, 2012 and 2011, the Company recognized expense associated

with its office leases in the amount of $1.0 million, $1.0 million, and $0.9 million, respectively.

Other. The Company is currently involved in various routine disputes and allegations incidental to its
business operations. While it is not possible to determine the ultimate disposition of these matters, management,
after consultation with legal counsel, is of the opinion that the final resolution of all such currently pending or
threatened litigation is not likely to have a material adverse effect on the consolidated financial position, results
of operations or cash flows of the Company.

12. CONCENTRATION OF CREDIT RISK:

The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of
trade receivables and commodity derivative contracts associated with the Company’s hedging program. The
Company’s revenues related to natural gas sales are derived principally from a diverse group of companies,
including major energy companies, natural gas utilities, oil refiners, pipeline companies, local distribution
companies, financial institutions and end-users in various industries.

79

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Concentrations of credit risk with respect to receivables is limited due to the large number of customers and
their dispersion across geographic areas. Commodity-based contracts may expose the Company to the credit risk
of nonperformance by the counterparty to these contracts. This credit exposure to the Company is diversified
primarily among as many as ten major investment grade institutions and will only be present if the reference
price of natural gas established in those contracts is less than the prevailing market price of natural gas, from time
to time.

The Company maintains credit policies intended to monitor and mitigate the risk of uncollectible accounts
receivable related to the sale of natural gas, condensate as well as its commodity derivative positions. The
Company performs a credit analysis of each of its customers and counterparties prior to making any sales to new
customers or extending additional credit to existing customers. Based upon this credit analysis, the Company
may require a standby letter of credit or a financial guarantee. The Company did not have any outstanding,
uncollectible accounts for its natural gas or oil sales, nor derivative settlements at December 31, 2013.

A significant counterparty is defined as one that individually accounts for 10% or more of the Company’s
total revenues during the year. In 2013, the Company had no single customer that represented 10% or more of its
total revenues.

13. SUBSEQUENT EVENTS:

The Company has evaluated the period subsequent to December 31, 2013 for events that did not exist at the
balance sheet date but arose after that date and determined that no subsequent events arose that should be
disclosed in order to keep the financial statements from being misleading.

15. DISCLOSURE ABOUT OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED):

The following information about the Company’s oil and natural gas producing activities is presented in

accordance with FASB ASC Topic 932, Oil and Gas Reserve Estimation and Disclosures:

A. OIL AND GAS RESERVES:

Our policies and practices regarding internal controls over the recording of reserves is structured to
objectively and accurately estimate our oil and gas reserves quantities and present values in compliance with the
SEC’s regulations and GAAP. The Vice President — Reservoir Engineering & Development is primarily
responsible for overseeing the preparation of the Company’s reserve estimates. He has a Bachelor and Master of
Science degree in Petroleum Engineering and is a licensed Professional Engineer with over 19 years of
experience. The Company’s internal controls over reserve estimates include reconciliation and review controls,
including an independent internal review of assumptions used in the estimation.

The estimates of proved reserves and future net revenue as of December 31, 2013, are based upon the use of
technical and economic data including, but not limited to, well logs, geologic maps, seismic data, well test data,
production data, historical price and cost information and property ownership interests. The reserves were
estimated using deterministic methods; these estimates were prepared in accordance with generally accepted
petroleum engineering and evaluation principles. Standard engineering and geoscience methods, such as
reservoir modeling, performance analysis, volumetric analysis and analogy,
that were considered to be
appropriate and necessary to establish reserve quantities and reserve categorization that conform to SEC
definitions and rules and regulations, were also used. As in all aspects of oil and natural gas evaluation, there are

in the interpretation of engineering and geoscience data;

therefore,

The determination of oil and natural gas reserves is complex and highly interpretive. Assumptions used to
estimate reserve information may significantly increase or decrease such reserves in future periods. The estimates
of reserves are subject to continuing changes and, therefore, an accurate determination of reserves may not be

possible for many years because of the time needed for development, drilling, testing, and studies of reservoirs.
From time to time, the Company may adjust the inventory and schedule of its proved undeveloped locations in
response to changes in capital budget, economics, new opportunities in the portfolio or resource availability. The
Company has not scheduled any proved undeveloped reserves beyond five years nor does it have any proved
undeveloped locations that have been part of its inventory of proved undeveloped locations for over five years.

The Company engaged Netherland, Sewell & Associates, Inc. (“NSAI”), a third-party,

independent
engineering firm, to prepare the reserve estimates for all of the Company’s assets in Wyoming and Pennsylvania
for the year ended December 31, 2013 in this annual report. This independent analysis conducted by NSAI
represents more than 98% of the Company’s proved reserves. Our internal professional staff works closely with
our independent engineers, NSAI, to ensure the integrity, accuracy and timeliness of data that is furnished to
them for their reserve estimation process. In addition, other pertinent data is provided such as seismic
information, geologic maps, well logs, production tests, well performance data, operating procedures and
relevant economic criteria. We make available all information requested, including our pertinent personnel, to the
external engineers as part of their evaluation of our reserves. The report of NSAI is included as an Exhibit to this
annual report.

The majority of the reserve estimates shown herein have been independently evaluated by Netherland,
Sewell & Associates, Inc. (NSAI), a worldwide leader of petroleum property analysis for industry and financial
organizations and government agencies. NSAI was founded in 1961 and performs consulting petroleum
engineering services under Texas Board of Professional Engineers Registration No. F-2699. Within NSAI, the
technical persons primarily responsible for preparing the estimates set forth in the NSAI reserves report
incorporated herein are Mr. Robert C. Barg and Mr. Phillip R. Hodgson. Mr. Barg has been practicing consulting
petroleum engineering at NSAI since 1989. Mr. Barg is a Licensed Professional Engineer in the State of Texas
(No. 71658) and has over 30 years of practical experience in petroleum engineering, with over 24 years’
experience in the estimation and evaluation of reserves. He graduated from Purdue University in 1983 with a
Bachelor of Science Degree in Mechanical Engineering. Mr. Hodgson has been practicing consulting petroleum
geology at NSAI since 1998. Mr. Hodgson is a Licensed Professional Geoscientist in the State of Texas, Geology
(No. 1314) and has over 29 years of practical experience in petroleum geosciences, with over 15 years’
experience in the estimation and evaluation of reserves. He graduated from University of Illinois in 1982 with a
Bachelor of Science Degree in Geology and from Purdue University in 1984 with a Master of Science Degree in
Geophysics. Both technical principals meet or exceed the education, training, and experience requirements set
forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information
promulgated by the Society of Petroleum Engineers; both are proficient in judiciously applying industry standard
practices to engineering and geoscience evaluations as well as applying SEC and other industry reserves
definitions and guidelines.

The Company closed on its acquisition of assets in Utah on December 12, 2013. Due to the timing of this
acquisition relative to the timing of preparing annual corporate reserves, the Company’s Reservoir Engineering
Department prepared the proved reserve estimates for its Utah assets. The proved reserve estimates were
estimated in accordance with the Company’s internal controls and SEC regulations. Furthermore, the reserves
estimated for the Utah assets are limited to proved developed wells as of December 31, 2013 and represent less
than 2% of the proved reserves disclosed in this report.

Since January 1, 2013, no crude oil or natural gas reserve information has been filed with, or included in any
report to, any federal authority or agency other than the SEC and the Energy Information Administration (“EIA”)
of the U.S. Department of Energy. We file Form 23, including reserve and other information, with the EIA.

C. STANDARDIZED MEASURE:

The following table sets forth a standardized measure of the estimated discounted future net cash flows
attributable to the Company’s proved natural gas reserves. Natural gas prices have fluctuated widely in recent
years. The calculated weighted average sales prices utilized for the purposes of estimating the Company’s proved
reserves and future net revenues at December 31, 2013, 2012 and 2011 was $3.51, $2.63 and $4.04 per Mcf,
respectively, for natural gas and $84.97, $87.85 and $88.19 per barrel, respectively, for oil and condensate, based
upon the average of the price in effect on the first day of the month for the preceding twelve month period.

The future production and development costs represent the estimated future expenditures to be incurred in
developing and producing the proved reserves, assuming continuation of existing economic conditions. Future
income tax expense was computed by applying statutory income tax rates to the difference between pretax net
cash flows relating to the Company’s proved reserves and the tax basis of proved properties and available
operating loss carryovers.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

There are numerous uncertainties inherent in estimating quantities of proved reserves and projected future
rates of production and timing of development expenditures, including many factors beyond the control of the
Company. The reserve data and standardized measures set forth herein represent only estimates. Reserve
engineering is a subjective process of estimating underground accumulations of oil and natural gas that cannot be
measured in an exact way and the accuracy of any reserve estimate is a function of the quality of available data
and of engineering and geological interpretation and judgment. As a result, estimates of different engineers often
vary. In addition, results of drilling, testing and production subsequent to the date of an estimate may justify
revision of such estimates. Accordingly, reserve estimates are often different from the quantities of oil and
natural gas that are ultimately recovered. Further, the estimated future net revenues from proved reserves and the
present value thereof are based upon certain assumptions, including geologic success, prices, future production
levels and costs that may not prove correct over time. Predictions of future production levels are subject to great
uncertainty, and the meaningfulness of such estimates is highly dependent upon the accuracy of the assumptions
upon which they are based. Historically, oil and natural gas prices have fluctuated widely.
