Oklahoma City, February 24, 2016 – Continental Resources, Inc. (NYSE: CLR) (the “Company”) today announced fourth quarter and full-year 2015 operating and financial results. Continental reported a net loss of $139.7 million, or $0.38 per diluted share, for the quarter ended December 31, 2015. Adjusted net loss for fourth quarter 2015 was $86.6 million, or $0.23 per diluted share.

For full-year 2015, the Company reported a net loss of $353.7 million, or $0.96 per diluted share. Adjusted net loss for full-year 2015 was $115.5 million, or $0.31 per diluted share.

EBITDAX for fourth quarter 2015 was $420.2 million, contributing to full-year 2015 EBITDAX of $1.98 billion. Definitions and reconciliations of adjusted net loss, adjusted earnings per share and EBITDAX to the most directly comparable U.S. generally accepted accounting principles (GAAP) financial measures can be found in the supporting tables at the conclusion of this press release.

“Our teams did an outstanding job in 2015 adjusting to market changes and working to align capital expenditures with cash flow. For 2016, we will remain patient and disciplined in our activities while striving to enhance shareholder value through continued improvements in our core plays, including our newest addition, the over-pressured STACK,” commented Harold Hamm, Continental’s Chairman and Chief Executive Officer.

He noted that three new wells in Oklahoma’s STACK play further demonstrate the outstanding potential of Continental’s leasehold position. “The Boden well was a significant step-out in southern Blaine County, and all three recent completions support our view of the upside of the over-pressured STACK Meramec formation,” Mr. Hamm said.

“Our SCOOP Woodford team has engineered a step-change increase in 90-day and 180-day production rates by applying enhanced completion techniques using increased proppant loading,” he said. “This has translated into higher estimated ultimate recoveries and made SCOOP an even more valuable growth platform.”

Production

Fourth quarter 2015 net production totaled 20.7 million barrels of oil equivalent (Boe), or 224,900 Boe per day, down slightly from third quarter 2015 and 16% higher than fourth quarter 2014. February 2016 production is expected to be approximately 225,000 Boe per day.

Total net production for the fourth quarter included 145,600 barrels of oil (Bo) per day (65% of production) and 476.2 million cubic feet (MMcf) of natural gas per day (35% of production). Full-year 2015 production averaged 221,700 Boe per day, an increase of 27% compared with full-year 2014.

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

Impressive New STACK Results Include 16-Mile Step-Out Well

The Company’s new STACK completions were the Boden 1-15-10XH, the Compton 1-2-35XH and the Blurton 1-7-6XH, all extended lateral tests targeting the over-pressured Meramec formation in Blaine County.

The Boden is a significant step-out test located 16 miles southwest of Continental’s first STACK well, the Ludwig 1-22-15XH. The Boden flowed at an impressive 24-hour initial production rate of 1,000 Bo and 15 MMcf of natural gas (3,508 Boe) from a 9,800-foot lateral. It is the Company’s deepest test of the Meramec reservoir to date, with the lateral section of the well positioned at an average vertical depth of 12,550 feet. Through the first 80 days of production, the Boden has continued to exhibit strong flowing casing pressure of more than 5,000 psi on a 20/64” choke.

The Compton and Blurton wells were closer step-out tests located five miles southwest and three miles northwest, respectively, of the Ludwig. The Compton flowed at an initial 24-hour production rate of 1,817 Bo and 4.4 MMcf of natural gas (2,547 Boe) from a 9,800-foot lateral. The Blurton flowed at an initial 24-hour production rate of 1,818 Bo and 3.1 MMcf of natural gas (2,328 Boe) from a 9,600-foot lateral.

“Our over-pressured Meramec wells in STACK are delivering some of the highest returns in the Company. We clearly have another high impact, long-term platform for growth underlying our 155,000 net acres of leasehold in STACK,” said Jack Stark, Continental’s President and Chief Operating Officer. “The

2

exceptional performance of these new wells supports our observation that over-pressured STACK wells produce on average three times more volume than wells in the normally-pressured STACK in their first 90 days, when normalized for a 9,800’ foot lateral. This is significant, as almost all of Continental’s STACK acreage is located in the over-pressured window.”

Based on early production from recent Continental completions and other non-operated wells in the over-pressured oil window, the Company is estimating an average estimated ultimate recovery (EUR) of 1.7 MMBoe per well. Continental is targeting a completed operated well cost of $10 million for a 9,800-foot lateral well, which would generate a 55% rate of return at $40 per barrel WTI and $2.25 per thousand cubic feet (Mcf) of natural gas.

The Company plans to average four-to-five operated drilling rigs in STACK in 2016, which would enable it to drill approximately 15 net (25 gross) operated wells and complete approximately nine net (15 gross) operated wells this year in the play. Continental’s STACK leasehold is primarily in Blaine, Dewey and Custer counties, and the Company anticipates more than 70% of it will be held by production by year-end 2016.

SCOOP Fourth Quarter Production Increases 60% Year over Year

In fourth quarter 2015, total SCOOP net production averaged 64,500 Boe per day, a 60% increase compared with the fourth quarter of 2014, and a 7% decrease sequentially compared with third quarter 2015, reflecting reduced completion activity. SCOOP production represented 29% of the Company’s total production in fourth quarter 2015, compared with 21% of Company production for fourth quarter 2014.

Of total SCOOP production, SCOOP Woodford net production averaged 54,100 Boe per day in fourth quarter 2015, or 84% of the total. SCOOP Springer net production averaged 10,400 Boe per day.

Continental completed eight net (38 gross) operated and non-operated wells in SCOOP in fourth quarter 2015, while operating an average of seven rigs in the play. Of these, the Company completed 7.5 net (36 gross) wells targeting the Woodford formation and 0.5 net (two gross) wells targeting the Springer formation.

For full-year 2015, Continental completed 74 net (204 gross) operated and non-operated SCOOP wells. These included 54 net (175 gross) wells targeting the Woodford, and 20 net (29 gross) wells targeting the Springer.

For all Oklahoma plays, Continental ended 2015 with approximately 35 gross operated wells drilled and uncompleted (DUCs) and plans to end 2016 with approximately 50 gross operated DUCs. The Company noted that its DUC inventory may also include wells that are drilled and completed, but not yet producing to sales.

SCOOP Woodford Enhanced Completions Deliver Step-Change Production Improvement

Continental has tested enhanced completions, primarily involving larger proppant volumes, on 15 SCOOP Woodford condensate wells. All are producing in excess of the Company’s standard type curve based on a 1.7 MMBoe EUR for a 7,500’ lateral. Enhanced completions have increased initial 90-day and 180-day production rates 30% to 35%, compared with offset wells. Based on the performance of the enhanced completed wells, the Company is increasing its SCOOP Woodford condensate EUR by 15% to 2.0 MMBoe per well.

3

The incremental cost for the large enhanced completions being done currently is approximately $400,000, bringing the completed well cost for these wells to approximately $9.9 million. This cost is expected to decline during 2016 to a targeted well cost of $9.6 million. At a target cost of $9.6 million, these wells generate a 25% ROR based on $40 per barrel WTI and $2.25 per Mcf of gas.

”We are encouraged by the results from our enhanced completions in SCOOP, and we continue to work to optimize our stimulation designs,” said Gary Gould, Senior Vice President of Production and Resource Development. “Our new type curves were built on data from initial enhanced completions with at least 90 days of production, and this well set had completion designs that averaged approximately 1,100 pounds of proppant per foot. More recently we’ve applied higher proppant concentrations averaging approximately 1,500 pounds per foot, and we’re seeing even higher early production from these higher sand volumes.”

SCOOP Woodford Density Test: Vanarkel Production Beats Enhanced Type Curve

Continental’s Vanarkel density project came online in fourth quarter 2015. Vanarkel involved seven gross (four net) wells that were stimulated with enhanced completions averaging approximately 1,500 pounds per foot of proppant. Early initial production for the Vanarkel wells is beating the Company’s updated SCOOP Woodford condensate type curve for enhanced completions. The wells flowed at an average total combined peak production rate of 52.4 MMcf and 4,980 Bo per day, or a total combined 13,713 Boe per day. Average peak production was 1,959 Boe per day per well in the project. Vanarkel production is 36% oil, comparable to the nearby Honeycutt density test.

The Vanarkel project was the Company’s third dual-level density pilot in the SCOOP Woodford condensate window, consisting of wells in the upper and lower Woodford, spaced 660 feet apart between well bores with approximately 100 feet of vertical separation. Average lateral length for the new Vanarkel wells was 7,400 feet.

SCOOP Springer

Continental participated in completing two notable non-operated wells targeting the Springer formation in fourth quarter 2015. The first non-operated well flowed at a rate of approximately 2,100 Boe (88% oil) per day, and the second was announced by its operator as flowing at a rate of 1,007 Boe (89% oil) per day.

Bakken DUC Inventory Growing in 2016

Continental’s Bakken production averaged 136,400 Boe per day in fourth quarter 2015, a slight increase over third quarter 2015.

The Company completed and initiated first sales for 22 net (105 gross) operated and non-operated Bakken wells during fourth quarter 2015, compared with a total 171 net (638 gross) operated and non-operated Bakken wells for full-year 2015. Continental’s operated wells with initial production in fourth quarter 2015 involved wells that had been previously drilled and completed, but not actively produced with first sales until the fourth quarter.

In 2015, the Bakken team doubled capital efficiency and cut finding costs in half. This was accomplished through a combination of inventory high-grading, cost reductions and operating efficiencies. The Company reduced average drilling time for spud-to-total-depth (TD) by 23% and average drilling cost by 33%, compared to fourth quarter 2014. The average spud-to-TD time in fourth quarter 2015 was 13.4 days for a well with a two-mile lateral, down from 17.4 days for fourth quarter 2014.

In 2016, the Bakken drilling program will continue to focus on high rate-of-return areas in McKenzie and Mountrail counties, targeting wells with an average EUR of 900,000 Boe per well. Based on the higher EUR and a lower targeted completed well cost of $6.7 million per well, the Company expects capital efficiency to increase 17% and finding cost to decrease 15% in 2016.

Given its plans to defer most Bakken completions in 2016, Continental expects to increase its Bakken DUC inventory to approximately 195 gross operated DUCs at year-end 2016. The year-end 2016 DUC inventory represents a high-graded inventory with an average EUR per well of approximately 850,000 Boe. At year-end 2015, the Company’s Bakken DUC inventory was approximately 135 gross operated DUCs.

The Company currently has four operated drilling rigs in the North Dakota Bakken and plans to maintain this level through year end. The Company currently has no stimulation crews deployed in the Bakken.

Financial Update

In fourth quarter 2015, Continental’s average realized sales price excluding the effects of derivative positions was $34.23 per barrel of oil and $2.07 per Mcf of gas, or $26.57 per Boe. Based on realizations without the effect of derivatives, the Company’s fourth quarter 2015 oil differential was $7.71 per barrel below the NYMEX daily average for the period. The fourth quarter 2015 realized wellhead natural gas price was on average $0.20 per Mcf below the average NYMEX Henry Hub benchmark price.

Production expense per Boe was $3.86 for fourth quarter 2015, a decrease of $1.45 per Boe from fourth quarter 2014. Other select operating costs and expenses for fourth quarter 2015 included production taxes of 7.8% of oil and natural gas sales; DD&A of $22.20 per Boe; and G&A (cash and non-cash) of $2.24 per Boe. On a full-year basis, these expense categories were within or better than guidance.

As of December 31, 2015, Continental’s balance sheet included $11.5 million in cash and cash equivalents and $853 million of borrowings against the Company’s revolving credit facility. Continental had approximately $1.9 billion in available borrowing capacity under its revolving credit facility as of December 31, 2015, and approximately $1.9 billion remains available at this time. The Company’s revolver is unsecured, and there are no terms in the facility that would mandate collateral or a borrowing base calculation coming back into place. The revolver’s sole financial covenant is a net debt to total capitalization ratio of no greater than 0.65, and as of December 31, 2015, the Company’s net debt to total capitalization ratio was 0.58. Under the terms of the credit agreement, the calculation of total capitalization specifically excludes any non-cash impairment charges incurred after June 30, 2014.

Non-acquisition capital expenditures for fourth quarter 2015 totaled $394.0 million, including $343.6 million in exploration and development drilling, $32.8 million in leasehold and seismic and $17.6 million in workovers, recompletions and other. Acquisition capital expenditures totaled $17.8 million for fourth quarter 2015.

Full-year 2015 non-acquisition capital expenditures totaled $2.5 billion, in line with commentary made on the third quarter 2015 earnings call. Acquisition capital expenditures totaled $61.0 million for the year.

John Hart, Continental’s Chief Financial Officer, commented, “We were very pleased to finish the year $200 million under our $2.7 billion budget, while still growing production 27% year-over-year. This speaks to the quality of our operating teams and assets. Looking ahead, our strategy is to stay focused on cash flow neutrality and maintaining our financial strength. We have ample liquidity with no near-term debt maturities.”

Continental’s 2016 guidance remains as announced on January 26, 2016 and can be found at the conclusion of this press release.

Non-GAAP Financial Measures

EBITDAX

We use a variety of financial and operational measures to assess our performance. Among these measures is EBITDAX. We define EBITDAX as 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, non-cash equity compensation expense, and losses on extinguishment of debt. 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. Further, 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. We exclude the items listed above from net income (loss) 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 (loss) 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.

The following table provides a reconciliation of our net income (loss) 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 losses on extinguishment of debt. 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 property dispositions. 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 tables reconcile 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.
