JONES ENERGY, INC. ANNOUNCES 2014 SECOND QUARTER FINANCIAL AND OPERATING RESULTS

Austin, TX — August 6, 2014 — Jones Energy, Inc. (NYSE: JONE) (“Jones Energy” or “the Company”) today announced financial and operating results for the quarter ended June 30, 2014.  For the quarter ended June 30, 2014, the Company reported a net loss of $9.2 million, adjusted net income of $20.5 million, and EBITDAX of $77.1 million.

2014 Second Quarter Highlights

·                  Successful frack trial outcome in the Cleveland with average oil uplift of more than 30%; increased 2014 capital expenditure budget to incorporate new Cleveland frack design for all remaining 2014 wells

·                  Increased average net production to a record 23.6 MBoe/d, up 41% compared to the same period in 2013

·                  Increased average net oil production to 7.2 MBbl/d, up 59% compared to the same period in 2013

·                  Increased Cleveland average net production to 16.8 MBoe/d, up 74% compared to the same period in 2013

·                  Raising full-year production guidance to 23.0 to 24.0 MBoe/d

·                  Increased EBITDAX to $77.1 million, up 45% compared to the same period in 2013

·                  Acquired more than 10,000 net acres of leasehold primarily in the Texas panhandle, effectively replacing all 2014 Cleveland drilling locations

·                  Initiated the Tonkawa drilling program with the first two wells in-line with budget and will allocate additional capital to maintain a full-time rig line during the second half of 2014

Jonny Jones, the Company’s Founder, Chairman and CEO commented, “The second quarter of 2014 was highlighted by a significant oil uplift from our 20 Cleveland frack trial wells.  The compelling economics provided by the trial have led us to increase the capital budget for 2014 in order to employ an enhanced frack technique for all Cleveland wells budgeted for the remainder of the year.  We have also had a very successful first six months in our current leasing program, replacing all of the 2014 Cleveland drilling locations by the end of the second quarter while spending barely half of our $22 million leasehold budget.”  Mr. Jones went on to say, “At this time last year, we were still celebrating the initial public offering of our common stock.  A brief twelve months later we have seen our rig count nearly double, our EBITDAX increase 45%, our oil production has grown 59%, and our overall production has increased more than 40%.  We are excited about our current growth trajectory and our outlook for the second half of 2014.”

Financial Results

Total operating revenues for the three months ended June 30, 2014 increased by $41.9 million to $106.4 million as compared to $64.5 million for the three months ended June 30, 2013.  The majority of the increase was due to increased oil production volumes with the remainder of the increase attributable to higher natural gas production volumes combined with higher prices for all products.

Total operating expenses for the three months ended June 30, 2014 increased by $23.4 million to $67.7 million as compared to $44.3 million for the three months ended June 30, 2013, primarily due to the increase in production volumes.  Specifically, lease operating expenses for the quarter were $12.4 million for the three months ended June 30, 2014 compared to $6.2 million for the three months ended June 30, 2013.  In addition to the effects of our significant oil production growth, the Company incurred approximately $0.7 million in non-recurring expenses associated with accrual adjustments stemming from our acquisition of properties from Sabine Mid-Continent, LLC and one-time costs related to wildlife habitat surveys for our Anadarko properties.  The Company has also continued to incur higher workover expenses associated with returning wells to production that were knocked off-line by offset frack operations.

Adjusted net income for the three months ended June 30, 2014 increased by $3.4 million to $20.5 million as compared to $17.1 million for the three months ended June 30, 2013, primarily due to the increase in production volumes and a small increase in the average realized price, partially offset by an increase in lease operating expenses and depletion, depreciation and amortization expense.

Operational Results

Cleveland

The Company spud 23 wells and completed 34 wells in the Cleveland in the second quarter of 2014.  As of June 30, 2014, 7 wells were in various stages of completion, and 7 wells were drilling.

Daily net production in the Cleveland was 16.8 MBoe/d in the second quarter of 2014, up 8% from the first quarter of 2014 and up 74% from the second quarter of 2013.  In addition to the increase in overall Cleveland production volumes, oil volumes increased by 11% when compared to the first quarter and were up 90% from the same period in 2013.

In the fourth quarter of 2013, the Company initiated a 20 well frack trial in the Cleveland formation utilizing a “plug and perf” completion technique with a design that utilized 20 stages and three perforation clusters per stage.  The purpose of the trial was to test the technical limits of frack density in the Cleveland formation.  The production figures thus far indicate well level economics that clearly support increased capital spending to achieve higher frack density in the Cleveland formation.

Our results indicate that the average frack trial well will yield a greater than 30% uplift in oil production, producing roughly 7,200 incremental barrels, through the first six months of production when compared to our historic 20 stage open-hole performance.  This additional oil production will provide a similar or better internal

rate of return (IRR) on incremental completion capital when compared to the overall IRR calculated for the 20 stage open-hole completion.  As a result, we believe that this completion technique has caused the value of our entire Cleveland drilling portfolio to increase significantly.

Based upon various factors observed during the completion and initial production phases of the wells in the frack trial, we do not believe that a frack was successfully initiated in all 60 perforation clusters.  In order to increase the certainty of frack initiation in all stages moving forward, the Company has already begun utilizing an enhanced frack technique.  Since transitioning to the enhanced frack technique, we have deployed over 180 independent frack stages with a near 100% frack initiation success rate.  In addition to the change in frack technique, the spacing between stages is expected to be normalized at roughly 100 feet, which equates to approximately 43 frack stages in the standard Cleveland lateral design.  Incremental completion costs per well, as compared to our historic 20 stage open hole design, are projected at approximately $0.9 million.  This will initially result in total costs of roughly $4.3 million to drill and complete wells using the new design and spacing, which is closely aligned with the company’s expectations at the outset of the Cleveland frack trial.  Utilizing our new design and enhanced frack technique we expect to meet or exceed the successful production results from our frack trial wells.

Tonkawa

The Company initiated its previously announced plan to drill a three well pilot program to test the Tonkawa formation in the second quarter of 2014.  Our target well cost for the Tonkawa is $3.5 million, $1 million less than the estimated industry average cost of $4.5 million.  At this time, we have reached TD and should be fracking the first of these wells by the middle of August.  We have spud the second well and are currently drilling.  Drilling costs for both wells appear to be in-line with our expectations.  At this time, the company is encouraged by the early drilling results and has decided to add additional capital to the Tonkawa program during the second half of the year.  The Company expects to maintain a dedicated rig line and drill five to six wells in the Tonkawa by year end.

Woodford

The Company spud 6 wells and completed 4 wells in the Woodford in the second quarter of 2014.  As of June 30, 2014, 7 wells were in various stages of completion, and 2 wells were drilling.

Net production in the Woodford was 4.2 MBoe/d in the second quarter of 2014 compared to 4.2 MBoe/d in the second quarter of 2013 and 3.2 MBoe/d in the first quarter of 2014.  Production was lower during the latter portion of 2013 and the first quarter of 2014 due to a pause in the drilling program during the middle of 2013.

The Company had previously disclosed its ongoing frack optimization tests in the Woodford involving more frack stages (16-20 vs. previous 10-14 stages) earlier this year.  While the Company has seen a modest increase in production due to the increase in frack stages, the production results have not been sufficient to justify the incremental capital to complete the additional frack stages.  In addition, due to several factors including

subsurface faulting, reservoir complexity, and fluid losses, our costs have exceeded our expectations.  We expect to spud the remaining 6 wells under our BP joint development agreement, however, we have agreed with Vanguard Natural Resources to suspend drilling on our Vanguard JDA while we further evaluate well results and methods to reduce well costs.

Under the terms of its agreement with Vanguard Natural Resources, the Company will need to drill three additional wells prior to April 2016 to retain future development opportunities covering the 10 township area of mutual interest (AMI).

Leasing

As of June 30, 2014, the Company had added just over 10,000 net acres, primarily in the Texas panhandle.  Having spent approximately 50% of the leasing budget thus far, our realized lease price has hovered just above $1,000 per acre.  Based upon five wells per section, the additional acreage provides 78 new drilling locations in the Cleveland formation alone.  This effectively replenishes all 2014 Cleveland drilling locations.  In addition, we have identified 56 new drilling locations spread across the Tonkawa and Marmaton formations.  Altogether, this provides 134 new drilling locations in multiple stacked formations across our core operating area.  The Company will continue with its leasing program during the second half of the year and expects to exhaust the remainder of the $22 million dollar leasing budget.

Capital Expenditures

During the second quarter of 2014, the Company spent $129.5 million, of which $117.5 million was related to drilling and completing wells, representing 91% of total capital expenditures in the quarter.  The table below summarizes the Company’s capital investment by area for 2Q14:

2Q14 Capital Expenditure Summary ($mm)

The Company recently increased its 2014 drilling and completion capital budget by approximately $110 million.  We now expect full year capital spending of $460 million.  The upward revision of the full year budget reflects the Company’s decision to move forward with the implementation of the enhanced frack technique for all remaining 2014 Cleveland wells, an increase to account for higher working interests in wells drilled in 2014, a

slightly faster than budgeted drilling and completion pace, and various cost overages experienced thus far in both the Cleveland and Woodford drilling programs.

Guidance

The Company is providing guidance for the third quarter and updated guidance for the full year 2014 as follows:

Liquidity

On April 1, 2014, the Company issued $500 million in aggregate principal amount of 6.75% senior unsecured notes due 2022 at an offering price equal to 100% of par. The Company received net proceeds of approximately $489 million, of which $160 million was used to repay all of the outstanding borrowings under its second lien term loan facility, with the remaining proceeds used to pay down borrowings under its senior secured revolving credit facility and increase working capital. After giving effect to this offering, the Company’s borrowing base on its senior secured revolving credit facility automatically decreased by $25 million to $550 million.  As of June 30, 2014, the Company held $31.8 million in unrestricted cash and had an undrawn credit facility balance of $300 million.

Non-GAAP Financial Measures and Reconciliations

EBITDAX is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies.

We define EBITDAX as earnings before interest expense, income taxes, depreciation, depletion and amortization, exploration expense, net gains (losses) on commodity derivatives (excluding current period settlements of matured derivative contracts), and other items.  EBITDAX is not a measure of net income as determined by United States generally accepted accounting principles, or GAAP.  Management believes EBITDAX is useful because it allows them to more effectively evaluate our operating performance and compare the results of our operations from period to period and against our peers without regard to our financing methods or capital structure.  We exclude the items listed above from net income 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 has limitations as an analytical tool and should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of our 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 historical costs of depreciable assets.  Our presentation of EBITDAX should not be construed as an inference that our results will be unaffected by unusual or non-recurring items and should not be viewed as a substitute for GAAP.  Our computations of EBITDAX may not be comparable to other similarly titled measures of other companies.

The following table sets forth a reconciliation of net income (loss) as determined in accordance with GAAP to EBITDAX for the periods indicated:

Jones Energy, Inc.

Non-GAAP Financial Measures and Reconciliations

Adjusted Net Income is a supplemental non-GAAP financial measure that is used by management and external users of the Company’s consolidated financial statements.  We define Adjusted Net Income as net income excluding the impact of certain non-cash items including gains or losses on commodity derivative instruments not yet settled, impairment of oil and gas properties, and non-cash compensation expense.  We believe adjusted net income and adjusted earnings per share are useful to investors because they provide readers with a more meaningful measure of our profitability before recording certain items for which the timing or amount cannot be reasonably determined.  However, these measures are provided in addition to, not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP.  The following table provides a reconciliation of net income (loss) as determined in accordance with GAAP to adjusted net income for the periods indicated:

(1) In arriving at adjusted net income, the tax impact of the adjustments to net income is determined by applying the appropriate tax rate to each adjustment and then allocating the tax impact between the controlling and non-controlling interests.

Non-GAAP Financial Measures and Reconciliations

Adjusted Earnings per Share is a supplemental non-GAAP financial measure that is used by management and external users of the Company’s consolidated financial statements.  We believe adjusted earnings per share is useful to investors because it provides readers with a more meaningful measure of our profitability before recording certain items for which the timing or amount cannot be reasonably determined.  However, these measures are provided in addition to, not as an alternative for, and should be read in conjunction with, the information contained in our financial statements prepared in accordance with GAAP.  The following table provides a reconciliation of earnings per share to adjusted earnings per share for the period indicated:
