JONES ENERGY, INC. ANNOUNCES 2013 FOURTH-QUARTER AND FULL-YEAR

FINANCIAL AND OPERATING RESULTS

Austin, TX — March 12, 2014 — Jones Energy, Inc. (NYSE: JONE) (“Jones Energy” or “the Company”) today announced financial and operating results for the quarter and full year ended December 31, 2013.  For the year ended December 31, 2013, the Company reported net income attributable to common stockholders of $22.4 million and EBITDAX of $205.0 million.

2013 Highlights

·                  Increased net production to 6.2 MMBoe (approximately 17.0 MBoe/d) in 2013, up 28% from 2012

·                  Increased EBITDAX by over 50% to $205.0 million in 2013 from $135.7 million in 2012

·                  Increased the pre-tax present value (“PV-10”) of the Company’s proved reserves to $1.0 billion, up 30% from year-end 2012

·                  Achieved drill-bit finding and development (“F&D”) cost of $15.01 per Boe in 2013(1)

·                  Increased Cleveland proved reserves by 42% from year-end 2012 to 57.5 MMBoe; additions replaced production by 558% (307% through the drill-bit)

·                  Acquired an additional 13.5 MMBoe of proved reserves and over 220 drilling locations in the Anadarko Basin for $193.5 million

(1) Drill-bit F&D defined as the total costs incurred for oil and natural gas properties, less property acquisition costs and asset retirement costs, divided by extensions and discoveries.

Jonny Jones, the Company’s Founder, Chairman and CEO commented, “2013 was a transformational year for Jones Energy.  We completed our initial public offering in July, expanded our core Cleveland position with our acquisition of assets from Sabine in December, and accelerated drilling activity from three rigs running just over a year ago to ten rigs currently running in our core operating areas.  We believe we are in an excellent position to deliver on our 2014 operating plan.”

Financial Results

Total operating revenues for the three months ended December 31, 2013 increased by $26.6 million (61%) to $70.3 million as compared to $43.7 million for the three months ended December 31, 2012.  The majority of the increase was due to higher crude 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 December 31, 2013 increased by $11.5 million (22%) to $65.0 million as compared to $53.4 million for the three months ended December 31, 2012, primarily due to the increase in production volumes.

Adjusted net income for the three months ended December 31, 2013 increased by $3.1 million (40%) to $10.9 million as compared to $7.8 million for the three months ended December 31, 2012, primarily due to the increase in production volumes and higher prices for all products.

Operational Results

Cleveland

The Company spud 23 Cleveland wells in the fourth quarter of 2013, four of which were completed as of December 31, 2013.  As of December 31, 2013, 14 wells were in various stages of completion, and eight wells were drilling.  The Company also completed nine Cleveland wells in the fourth quarter that were carried over from prior periods.

Daily net production in the Cleveland was approximately 10.8 MBoe/d in the fourth quarter of 2013, up 2% from the third quarter of 2013 and up 43% from the fourth quarter of 2012.  Fourth quarter production was negatively impacted by severe winter weather and offset frack impacts, including production delays tied to a new completion design tested in the Cleveland formation beginning in late 2013.  The Company estimates these factors impacted Cleveland production in the fourth quarter of 2013 by approximately 1.6 MBoe/d, 0.5 MBoe/d due to weather and 1.1 MBoe/d due to offset frack impacts and completion timing, most of which will be deferred to future periods.

For the month ended December 31, 2013, daily net production in the Cleveland averaged approximately 10.9 MBoe/d, including approximately 1.0 MBoe/d attributable to the assets acquired from Sabine, which produced 2.2 MBoe/d for the 14 days in 2013 after the acquisition closed.  The Company is continuing to collect data from the 20 well enhanced frack test in the Cleveland.  Over the next two quarters, the Company will monitor production data on the test wells and undertake additional optimization techniques, prior to making a decision on whether the level of production is significant enough to justify the incremental capital investment per well, and which design to utilize going forward.

Woodford

The Company spud eight Woodford wells in the fourth quarter of 2013, none of which were completed as of December 31, 2013.  These wells have been undergoing batch completion operations and are expected to be completed in the first and second quarters of this year.

Daily net production in the Woodford was 4.1 MBoe/d in the fourth quarter of 2013, up 5% from the third quarter of 2013, but down 18% from the fourth quarter of 2012.  The production decrease compared to the fourth quarter of 2012 was primarily due to the Company’s pause in drilling over the majority of the first three quarters of 2013.

The Company currently has two rigs running in the Woodford and may add rigs in the second half of 2014, depending upon the results of its frack optimization tests, which involve more frack stages (16 — 20 vs. previous 10 — 14 stages).

The Company is updating its Woodford AFE to incorporate changes in well design and completion technique.  The Company projects its average AFE in the northern part of the play to be $4.5 million.  In the southern part of the play, the Company’s costs are expected to remain the same at $3.3 million.  The majority of the increase is due to higher stimulation costs for the larger frack jobs ($0.5 million) and the use of intermediate casing ($0.3 million).  The Company will continue to evaluate the results of the frack optimization tests and will provide an update on its 2014 Woodford development plan when sufficient data on production results from the frack test are available.

Capital Expenditures

During the fourth quarter of 2013, the Company spent $86 million, of which $79 million was related to drilling and completing wells, representing 92% of total capital expenditures in the quarter.  The table below summarizes the Company’s capital investment by area for 2013:

2014 Guidance

The Company entered 2014 with ten rigs running in its core operating areas and may add rigs in the second half of the year.  In order to generate growth above its base plan, Jones expects to begin a three well test in the Tonkawa formation in the second quarter of 2014.  The Company expects to drill the following wells in 2014:

2014 Development Drilling Plan 

Of the 25 gross wells the Company expects to drill in the Woodford in 2014, six will be under its partnership with Vanguard Natural Resources and 12 will be under its partnership with BP.  Based on the Company’s 2014 development plan, it expects to fulfill its minimum drilling requirements under its partnerships with Vanguard Natural Resources and BP by the end of the third quarter of this year.

The Company reiterates its 2014 guidance initially provided in February and is also providing production guidance for the first quarter of 2014, which is above the Company’s initial expectations:

Non-GAAP Financial Measures and Reconciliations

($ in thousands)

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

(Values in thousands, except per share data)

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 net income per diluted 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:

Earnings per share

(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.
