OKLAHOMA CITY, Nov. 6, 2013 /PRNewswire/ — Continental Resources, Inc. (NYSE: CLR) (“Continental” or the “Company”) announced third quarter 2013 operating and financial results, reporting net income of $167 million, or $0.91 per diluted share. Adjusted net income, which excludes items typically excluded from published analyst estimates, totaled $297 million, or $1.61 per diluted share, an increase of $51 million compared to second quarter 2013. The Company achieved record EBITDAX of $798 million, an increase of $89 million or 13% compared to second quarter 2013. Definitions and reconciliations of adjusted net income, adjusted earnings per share and EBITDAX to the most directly comparable U.S. GAAP financial measures can be found in the supporting tables at the conclusion of this release.

Third quarter 2013 production highlights include:

Harold G. Hamm, Continental’s Chairman and Chief Executive Officer commented, “The Continental team performed at an exceptional level in the third quarter of this year, increasing production, generating record EBITDAX and delivering on budget. In addition, we completed our first density test in the Hawkinson spacing unit, demonstrating very strong initial production in the Middle Bakken and the first three benches of the Three Forks. Once again, Continental is pioneering the expansion and improved recoveries in the world-class Bakken oil play, demonstrating the productive potential of four to five stacked zones with multiple wells in each.”

Bakken Delivers Oil Growth

Net production from the Company’s industry-leading activity in the Bakken play in North Dakota and Montana increased to approximately 94,500 Boe per day in third quarter 2013, an increase of 7% sequentially and 51% above third quarter 2012. The Company’s gross operated Bakken production averaged approximately 119,000 Boe per day in third quarter 2013. In the third quarter 2013, Continental operated an average of 20 rigs across its leasehold position of approximately 1.2 million net acres in the Bakken play.

The Company participated in completing 75 net (203 gross) wells in third quarter 2013. Given the company’s increased activity on large drilling pads, the amount of gross operated wells drilled, but not yet completed increased in third quarter 2013 and is currently 85 wells.

Drilling and completion costs continued to improve in the Bakken in the third quarter. Continental’s average operated completed well cost in North Dakota is now $8.0 million per well, achieving its revised year-end target two months ahead of schedule. The Company’s original operated well cost target for 2013 was $8.2 million per well, which was later reduced to $8.0 million per well.

Bakken Downspacing Activity: The Hawkinson Unit

In October 2013 and one month ahead of schedule, Continental successfully completed the first of four pilot density projects it has under way. The Hawkinson unit initially tested at a combined rate of 14,850 Boe per day from 14 wells. This included 13,400 Boe per day from 11 new wells drilled this year and combined current rates of 1,450 Boe per day from three existing wells in the unit, which to-date have cumulative production of 1.3 million Boe since 2010. The Hawkinson density project includes four Middle Bakken, three TF1 (Three Forks 1), four TF2 and three TF3 wells, which all were spaced 1,320 feet apart in the same zone and offset 660 feet in the adjacent zones. This is the industry’s first density drilling program in the basin to include all of these lower benches.

W. F. “Rick” Bott, Continental’s President and Chief Operating Officer, commented, “The Hawkinson project is a milestone event for CLR and further validates our vision for full field development of the Bakken –Three Forks reservoirs in this world class oil field. Clearly there is more oil to be recovered than previously perceived and projects like the Hawkinson are leading the way to defining the optimum drilling density and pattern to maximize oil recovery. The news in the Bakken just keeps getting better.”

In addition to the Hawkinson project, Continental has three other density pilot tests in North Dakota underway, with results expected in the first half of 2014. The Tangsrud project in Divide County involves 12 new wells and the Rollefstad project in McKenzie County involves 11 new wells drilled with 1,320 foot same zone inter-well spacing, similar to the Hawkinson. The Wahpeton project in McKenzie County involves 13 new wells configured in four zones at tighter spacing, which is 660 foot same zone inter-well spacing. During 2014, Continental plans to conduct three additional density pilots to test 660 foot inter-well spacing, further defining the density spacing across a very large portion of Continental’s acreage in the Bakken.

The Company plans to complete approximately 282 net (761 gross) wells in the Bakken in 2013, including both operated and non-operated wells. The Company estimates its operated rig activity will average 20 rigs throughout the balance of 2013, down from 22 rigs as earlier expected due to realized efficiencies. This activity level should deliver the planned production growth and stay within capital expenditure guidance.

Full Development Planned for Antelope – “Ears Back” Program

The Antelope prospect area in McKenzie and Williams Counties, North Dakota will be the first area Continental will execute full field development activities in the Bakken as part of the 2013-2014 planned capital program. The Company currently has 40 gross existing producing wells in this area, which includes the recently completed prolific Angus wells and legacy activity at the Rollefstad density pilot. The Company plans to drill an additional 350 wells over the course of the next four to five years focusing on drilling pads with 20 to 30 wells per location. Continental’s “Ears Back” project in Antelope will dedicate four rigs in 2014 for full field development with plans to drill Middle Bakken, TF1, TF2 and TF3 wells with 1,320 foot inter-well spacing.

Hamm added, “Antelope is a high-impact area where we have been eager to expand our activity, however, we needed to allow regional infrastructure to catch up to support our goal of limited natural gas flaring. We are already leveraging on the success of the Hawkinson project in Antelope with well

placement, completion design and facility planning for up to 30 wells on a single location. This area will be the first in the field to see full field development including the deeper TF benches.”

Growth in SCOOP Continues

Continental continues to deliver excellent, repeatable results from its drilling activity in the SCOOP. The play, discovered by Continental and announced in October 2012, currently extends approximately 3,300 square miles across several counties in Oklahoma and contains defined oil and condensate-rich fairways as delineated by more than 290 gross wells in the area. Continental currently has approximately 320,000 net acres of leasehold in the play. In third quarter 2013, SCOOP net production averaged approximately 20,100 Boe per day, an increase of 14% sequentially and 293% above third quarter 2012. The recent growth was driven by the addition of 11 net (22 gross) operated and non-operated wells in the play during the third quarter 2013, as per the Company’s capital plan.

The Company is currently operating 12 rigs in the play with plans to increase to 15 by year-end 2013. The Company plans to complete a total of approximately 41 net (77 gross) wells in the SCOOP play in 2013, including both operated and non-operated wells. These wells will focus on expanding the proved productive extent of the play and de-risking the Company’s leasehold. Expected net and gross well count activity has been adjusted to account for recent increased cross-unit activity.

Production

Third quarter 2013 Company net production totaled 13.1 million Boe, or approximately 141,900 Boe per day, a sequential increase of 5% from second quarter 2013. Total net production included approximately 100,700 barrels of oil per day (71% of production) and approximately 247 million cubic feet of natural gas per day (29% of production). In the third quarter 2013, the Company sold its natural gas prior to processing based upon pricing provisions in its natural gas contracts. The Company estimates that if it had sold its natural gas liquids after processing, the combined natural gas liquids and oil would account for approximately 80% of total production.

The following table provides the Company’s average daily production by region for the periods presented.

Financial Update

Continental’s average realized sales price excluding the effects of derivative positions was $98.02 per barrel of oil and $5.23 per thousand cubic feet (“Mcf”) of natural gas, or $78.55 per Boe for third quarter 2013. Realized settlements of commodity derivative positions generated a $5.92 loss per barrel of oil and $0.62 gain per Mcf of natural gas resulting in a net realized hedging loss of $40.3 million, or $3.11 per Boe for the third quarter 2013. Based on realizations without the effect of derivatives, the Company’s third quarter 2013 oil differential was $7.80 per barrel below the NYMEX daily average for the period. The realized natural gas price differential for third quarter 2013 was a positive $1.65 per Mcf.

Production expense per Boe was $5.17 for third quarter 2013, an improvement of $0.69 per Boe compared to second quarter 2013. Other select operating costs and expenses for third quarter 2013 included production taxes of 8.2% of oil and natural gas sales; DD&A of $18.87 per Boe; and G&A (cash and non-cash, excluding relocation expenses) of $2.62 per Boe. The Company’s 2013 and 2014 guidance can be found at the conclusion of this release.

As of September 30, 2013, Continental’s balance sheet included approximately $92 million in cash and cash equivalents and an undrawn $1.5 billion revolving credit facility. During third quarter 2013, the Company’s long-term corporate credit rating and senior unsecured debt was increased by Standard & Poor’s to BBB-, which is investment grade status. As of September 30, 2013, the Company’s Net Debt-to-EBITDAX ratio for the trailing four quarters and third quarter 2013 annualized was 1.6 and 1.4 times, respectively.

Non-acquisition capital expenditures for third quarter 2013 totaled $910 million, including $770 million in exploration and development drilling, $100 million in leasehold and seismic and $40 million in workovers, recompletions and other. Acquisition capital expenditures totaled approximately $74 million for third quarter 2013, and are excluded from the Company’s capital expenditure guidance for 2013 of $3.6 billion.

The following table provides the Company’s production results, average sales prices, per-unit operating costs, results of operations and certain non-GAAP financial measures for the periods presented. Average sales prices exclude any effect of derivative transactions. Per-unit expenses have been calculated using sales volumes.

Non-GAAP Financial Measures

EBITDAX

EBITDAX represents earnings before interest expense, income taxes, depreciation, depletion, amortization and accretion, property impairments, exploration expenses, non-cash gains and losses resulting from the requirements of accounting for derivatives, and non-cash equity compensation expense. EBITDAX is not a measure of net income or operating cash flows as determined by U.S. GAAP.

Management believes EBITDAX is useful because it allows us to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above from net income and operating cash flows in arriving at EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired.

EBITDAX should not be considered as an alternative to, or more meaningful than, net income or operating cash flows as determined in accordance with U.S. GAAP or as an indicator of a company’s operating performance or liquidity. Certain items excluded from EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of EBITDAX. Our computations of EBITDAX may not be comparable to other similarly titled measures of other companies.

We believe EBITDAX is a widely followed measure of operating performance and may also be used by investors to measure our ability to meet future debt service requirements, if any. Our credit facility requires that we maintain a total funded debt to EBITDAX ratio of no greater than 4.0 to 1.0 on a rolling four-quarter basis. This ratio represents the sum of outstanding borrowings and the letters of

credit under our credit facility plus our note payable and Senior Note obligations, divided by total EBITDAX for the most recent four quarters. Our credit facility defines EBITDAX consistent with the presentation below. The following table provides a reconciliation of our net income to EBITDAX for the periods presented.

The following table provides a reconciliation of our net cash provided by operating activities to EBITDAX for the periods presented.

Adjusted earnings and adjusted earnings per share

Our presentation of adjusted earnings and adjusted earnings per share that exclude the effect of certain items are non-GAAP financial measures. Adjusted earnings and adjusted earnings per share represent earnings and diluted earnings per share determined under U.S. GAAP without regard to non-cash gains and losses on derivative instruments, property impairments, gains and losses on asset sales, and corporate relocation expenses. Management believes these measures provide useful information to analysts and investors for analysis of our operating results on a recurring, comparable basis from period to period. In addition, management believes these measures are used by analysts and others in valuation, comparison and investment recommendations of companies in the oil and gas industry to allow for analysis without regard to an entity’s specific derivative portfolio, impairment methodologies, and nonrecurring transactions. Adjusted earnings and adjusted earnings per share should not be considered in isolation or as a substitute for earnings or diluted earnings per share as determined in accordance with U.S. GAAP and may not be comparable to other similarly titled measures of other companies. The following table reconciles earnings and diluted earnings per share as determined under U.S. GAAP to adjusted earnings and adjusted diluted earnings per share

for the periods presented.
