Jonny Jones, the Company’s Founder, Chairman and CEO commented, “2015 is off to a great start for Jones Energy.  We are well-hedged, well-capitalized, and well-positioned with an operating plan that maximizes returns for our invested capital and provides us with the opportunity to grow the company via multiple avenues.  We have resolved our production issues that negatively impacted our fourth quarter production and as a result, have seen production increase by roughly 3,000 barrels of oil equivalent per day in January 2015.  In addition, we are continuing to see drilling and completion costs come down in our core Cleveland play and are prepared to ramp

activity from three rigs to five rigs assuming we achieve additional targeted cost savings by mid-year.”  Mr. Jones went on to say, “Over the past 26 years since I founded Jones Energy, we have experienced multiple commodity price cycles.  I believe that this is the kind of environment where Jones Energy thrives.”

Financial Results

Total operating revenues for the three months ended December 31, 2014 increased by $5.3 million, or 8%, to $75.6 million as compared to $70.3 million for the three months ended December 31, 2013.  The increase was due to increased production volumes for all commodities.  For the full-year 2014, operating revenues increased by $121.4 million, or 47%, to $380.6 million as compared to $259.2 million for the full-year 2013, primarily due to increased production volumes for all commodities.

Total operating expenses for the three months ended December 31, 2014 were unchanged at $65.0 million as compared to $65.0 million for the three months ended December 31, 2013.  Increased production would have resulted in higher operating costs year over year, but the impairment charge related to the termination of the Southridge joint development agreement which occurred during the three month period ended December 31, 2013 did not recur during the same period in 2014.  For the full-year 2014, operating expenses increased by $70.2 million, or 35%, to $273.6 million as compared to $203.4 million for the full-year 2013, primarily due to increased production volumes.

Adjusted net income for the three months ended December 31, 2014 increased by $3.4 million, or 31%, to $14.3 million as compared to $10.9 million for the three months ended December 31, 2013, with increased production volumes primarily responsible for the increase in both revenues and operating expenses.  Adjusted net income for the full-year 2014 increased by $9.4 million, or 17%, to $64.2 million as compared to $54.8 million for the full-year 2013.

Operational Results and Updates

Cleveland

The Company spud 31 wells and completed 28 wells in the Cleveland in the fourth quarter of 2014.  As of December 31, 2014, 18 wells were in various stages of completion, and eight wells were drilling.  Full-year production in the Cleveland was 17.0 MBoe/d for 2014, an increase of 7.0 MBoe/d, or 70%, from 2013 full-year production of 10.0 MBoe/d.

Daily net production in the Cleveland was 17.2 MBoe/d in the fourth quarter of 2014, down 6% from the third quarter of 2014 and up 59% from the fourth quarter of 2013.  Fourth quarter production was negatively impacted by continued delays in well completions and sand flow back issues.  In addition, December production was impacted by more than 1,000 Boe per day due to field production issues, including an outage at a third party processing facility.

During January 2015, the Company achieved record single day wellhead production reaching over 29,000 Boe/d.  Average daily production for January 2015 was approximately 3,000 Boe/d higher than December of 2014.  The significant jump in average daily production between December 2014 and January 2015 was primarily attributable to closing the timing gap between drilled wells and completed wells.

Tonkawa

The Company spud two wells and completed two wells in the Tonkawa in the fourth quarter of 2014.  As of December 31, 2014, two wells were being completed, and zero wells were being drilled.  Under the Company’s current 2015 budget and operating plan, Jones Energy does not plan to drill any additional Tonkawa wells in 2015.

Woodford

The Company spud one well and completed four wells in the Woodford in the fourth quarter of 2014.  As of December 31, 2014, four wells were being completed, but no wells were being drilled, as we released our last Woodford rig in November 2014.  Under the Company’s current 2015 budget and operating plan, Jones Energy does not plan to drill any Woodford wells in 2015.

Net production in the Woodford was 4.5 MBoe/d in the fourth quarter of 2014, up 13% from the third quarter of 2014 and up 8% from the fourth quarter of 2013.  Full-year production in the Woodford was 4.0 MBoe/d, a slight decrease of 0.1 MBoe/d, or 2%, from 2013 full-year production of 4.1 MBoe/d.

Capital Expenditures

During the fourth quarter of 2014, the Company spent $152.9 million, of which $130.1 million was related to drilling and completing wells, representing 85% of total capital expenditures in the quarter.  The table below summarizes the Company’s capital investment by area for 2014:

2014 Capital Expenditure Summary ($mm)

2015 Capital Budget and Operating Plan

The Company has established a capital budget of $210 million for 2015, with approximately $190 million dedicated to Cleveland drilling and completion activity and the remainder allocated to capital work-overs and field maintenance projects.  This budget represents a nearly 60% reduction in capital expenditures from 2014 and provides for a development program which keeps capital spending within expected cash flow.  The Company will continue at its current three rig pace during the first portion of the year, and assuming targeted additional cost reductions for drilling and completions are achieved, will deploy two additional rigs to the Cleveland to reach a five rig pace by mid-year.  The Company’s average estimated cost to drill and complete a Cleveland well with its 33 stage open-hole design has been reduced to approximately $2.9 million, creating $900,000 in cost savings, or a 24% cost decrease, compared to the $3.8 million estimate provided during December 2014.  The Company continues to actively negotiate with its various service providers and expects that additional cost savings can be attained.

2015 Guidance

We are reiterating our 2015 guidance for the first quarter and full-year.  We project full-year 2015 average daily production of between 21,700 and 23,700 Boe/d.  First quarter 2015 production is projected between 24,000 and 25,000 Boe/d.  Under the current operating plan, production will peak during the first quarter and flatten during the second half of the year.  Assuming targeted cost reductions are achieved and additional rigs are deployed, capital spending is expected to be $210 million for the full-year.  First quarter capital expenditures are expected to be higher than the rest of the year, much like production, due to carry-over activity from late 2014, primarily well completions.  For 2015, the company expects to drill between 60 and 70 gross wells with an average working interest of approximately 80%.  Due to carry-over of drilled but uncompleted wells from 2014, the Company expects to complete between 70 and 80 wells during 2015, also with an average working interest of approximately 80%.

Liquidity and Hedging

In February 2015, the Company completed three transactions which substantially improved its liquidity: a public offering of approximately $77 million of common stock, a private placement of $50 million of common stock, and a private placement of $250 million principal amount of senior notes.  As a result of the debt offering, the Company’s borrowing base was reduced to $562.5 million.  As of March 2, 2015, the Company held $26.9 million in unrestricted cash and had an undrawn credit facility balance of $482.5 million, resulting in pro-forma liquidity of $509.4 million.

The Company has provided updated hedge positions.  The estimated market value of our hedges was $208.5 million as of December 31, 2014.  The following table summarizes the Company’s commodity derivative contracts outstanding as of December 31, 2014:

Information Concerning Proved Reserves

Proved reserves volumes and related PV-10 values as of December 31, 2014 contained herein are based on SEC mandated first-day-of-the-month unweighted average prices for 2014 and costs as of December 31, 2014. These prices and costs are not representative of current market values and do not fully reflect declines in such prices and costs which have occurred since mid-year 2014. PV-10 is a non-GAAP financial measure and generally differs

7

from Standardized Measure, the most directly comparable GAAP financial measure, because it does not include the effect of income taxes on discounted future net cash flows. Neither PV-10 nor Standardized Measure represents an estimate of the fair market value of our oil and natural gas properties. The oil and gas industry uses PV-10 as a measure to compare the relative size and value of proved reserves held by companies without regard to the specific tax characteristics of such entities. See “Reconciliation of PV-10 to Standardized Measure” below.

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:
