Reverse Stock Split

During the third quarter of 2018 Jones Energy’s Board of Directors approved and implemented a 1-for-20 reverse stock split for the Company’s Class A and Class B Common Stock, which had previously been approved by common stockholder vote at the Company’s Annual Meeting in May 2018. The reverse stock split became effective September 7, 2018 at 5:00 pm Eastern Time. The shares of Class A common stock continued trading on the New York Stock Exchange (“NYSE”) without interruption and began trading on a split-adjusted basis on September 10, 2018. As a result of its implementation, Jones Energy cured its previously announced stock price deficiency with the NYSE on September 21, 2018.

Preferred Dividend Update

On July 17, 2018, the Company’s Board of Directors declared a contingent dividend on the Company’s 8.0% Series A Perpetual Convertible Preferred Stock (“Preferred Stock”), payable in Class A common stock on August 15, 2018 to holders of record as of August 1, 2018. It was announced on August 15, 2018 that the Dividend Valuation Price did not meet the required Floor Price(2), and the dividend was not paid. The right to receive that dividend accrued for holders of Preferred Stock.

On October 15, 2018 the Company’s Board of Directors declared a contingent dividend on the Preferred Stock under the same terms, payable in Class A common stock on November 15, 2018 to holders of record as of November 1, 2018, including the requirement that the Dividend Valuation Price of the stock must meet the required Floor Price, which has been adjusted for the Company’s 1-for-20 reverse stock split, in order to be paid. If the dividend is not paid, the Company will have used three of its five permitted dividend non-payments without penalty and the right to receive the dividend will again accrue for holders of Preferred Stock.

(2)  As defined in the Certificate of Designations for the Preferred Stock and as adjusted in accordance with the terms of the Certificate of Designations.

Operating Results

During the third quarter of 2018 Jones Energy produced 2.0 MMBoe, or 21,750 Boe/d, which was at the high end of guidance, supported by natural gas and NGL outperformance. Third quarter oil volumes of 5,587 Bbls/d were within Company guidance. A breakout of third quarter production is shown in the table below.

Merge

During the third quarter of 2018, the Company spud three wells and completed three wells in the Merge. Of the three wells completed, two were Meramec and one was a Woodford.  Third quarter Merge production of 7,837 Boe/d reflects the Company’s slowdown in activity and is indicative of having fewer completions during the quarter as compared to the first two quarters of 2018. The Company currently has three wells, including its remaining two HBP operated wells, in various stages of completion which are expected to be placed online during the fourth quarter.

Western Anadarko Basin (WAB)

During the quarter, the Company completed two wells, including its first operated Marmaton well in Ochiltree County, the Malinda 2H, which began flowback in early August. The Malinda 2H achieved a peak three-stream IP30 rate of 582 Boe/d, consisting of 62% oil and 77% liquids. The Company is encouraged by these strong early production rates and will continue to selectively drill additional Marmaton targets.

During the third quarter of 2018, Jones Energy also spud two wells in the WAB (one Cleveland, one Marmaton). The Company anticipates completing both wells during the fourth quarter. Jones Energy had one rig working during the third quarter but expects to have limited WAB activity during the fourth quarter of 2018.

Capital Expenditures

During the third quarter of 2018, the Company spent $43.6 million on capital expenditures, of which $36.4 million, or 84% of total capital expenditures, was related to drilling and completion (“D&C”) capital. Operated D&C capital expenditures was $30.9 million and third-party non-operated D&C capital expenditures was $5.5 million. The remaining $7.2 million of capital expenditures for the quarter was related to leasing and

maintenance. Capital expenditures for the first nine months of 2018 totaled $154.1 million, of which year-to-date third party non-operated drilling and completion capital was $22.6 million.

Initial 2018 Fourth Quarter Guidance

Jones Energy is announcing projected average daily production of 19,400 to 20,400 Boe/d for the fourth quarter of 2018. The Company is focused on completing its HBP Merge program, which includes two of the three completions that are anticipated during the fourth quarter. These completions are expected to have minimal impact on the Company’s production during the fourth quarter but should meaningfully contribute to production in early 2019. Jones Energy expects limited WAB activity for the remainder of the year. As a result of the anticipated fourth quarter Merge completion activity and increased working interest capital in wells drilled prior to the quarter, expenditures for the fourth quarter of 2018 are anticipated to be between $38 million and $43 million. A table has been provided below with production guidance by category.

Liquidity and Hedging

As of September 30, 2018, Jones Energy had approximately $94 million in cash. As previously announced, the Company continues to explore strategic alternatives and debt reduction initiatives, including the potential divestment of certain noncore assets and further borrowing as permitted under the Company’s indentures.

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, gains and losses from derivatives less the current period settlements of matured derivative contracts, and the other items described below.  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:

Non-GAAP Financial Measures and Reconciliations

Adjusted net income (loss) 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 (loss) 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, non-cash compensation expense, and the other items described below.  We believe adjusted net income (loss) and adjusted earnings (loss) 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 (loss) for the periods indicated:

Non-GAAP Financial Measures and Reconciliations

Adjusted earnings (loss) 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 define adjusted earnings (loss) per share as earnings (loss) per share plus that portion of the components of adjusted net income (loss) allocated to the controlling interests divided by weighted average shares outstanding.  We believe adjusted earnings (loss) 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 (loss) per share to adjusted earnings (loss) per share for the period indicated:
