Jonny Jones, the Company’s Founder, Chairman and CEO stated, “At the beginning of 2015, we set the goals of protecting our balance sheet and executing a focused capital development plan.  We took care of the balance sheet and our liquidity needs in the first quarter while beginning our cost reduction efforts.  During the second quarter, we continued to drive down costs which allowed for the addition of two rigs at mid-year as previously planned.  Individual well cost during the second quarter reached our target AFE of $2.6 million ahead of schedule.  As a result, we have maintained a high level of liquidity, a strong production profile and are on track with our capital expenditure expectations through the first half of the year.  As the year has progressed, we have achieved higher rig utilization by acquiring additional working interest, allowing for location capture at minimal cost.  As a result of the working interest capture and production outperformance, we have increased guidance for this year.  We are now beginning to test the leasing market which we believe may provide attractive opportunities for additional growth.  As previously discussed, we are continuing to

evaluate joint ventures and asset acquisitions as recent market activity seems to indicate that more high quality opportunities are making their way into the market.  We have remained busy during the quarter reviewing and high grading what we believe could be the most accretive and beneficial paths to increasing shareholder value.”

Mr. Jones went on to say, “Recent commodity price movements reflect the ‘lower for longer’ potential which was a significant factor in our decision to take advantage of the capital markets during the first quarter of the year.  Reducing our overall leverage while simultaneously moving the majority of the balance of our credit facility to term debt has provided us with a significant increase in financial flexibility should the lower price environment persist.  Should commodity prices deteriorate to the point where acceptable margins are unattainable, we will revisit our capital allocation decisions.  Our goal is always to create the best possible return for our shareholders.  We are poised to move in whichever direction necessary to protect our stakeholders’ interests while capitalizing on opportunities.  We have executed as promised during the first half of the year and are excited about our prospects for the remainder of 2015.”

Financial Results

Total operating revenues for the three months ended June 30, 2015 were $53.9 million as compared to $106.4 million for the three months ended June 30, 2014.  The decrease was due to lower commodity prices, which was somewhat offset by higher production.

Total operating expenses for the three months ended June 30, 2015 were $77.4 million as compared to $70.3 million for the three months ended June 30, 2014.  The increase was primarily due to increased production which resulted in higher lease operating and depletion, depreciation, and amortization expenses (“DD&A”).  The Company also incurred certain non-recurring charges which were included in other operating expenses.

For the three months ended June 30, 2015, the Company reported an adjusted net loss of $0.2 million as compared to adjusted net income of $18.2 million for the three months ended June 30, 2014.  The decrease was primarily due to lower average realized prices for all commodities and a slight increase in overall operating expenses, which was primarily related to higher DD&A expenses resulting from higher production volumes.

Operational Results

Cleveland

The Company’s second quarter development activity was focused exclusively on the Cleveland.  During the second quarter, the Company spud 15 wells and completed 14 wells, with a total of 11 wells seeing first production during the quarter.  As of June 30, 2015, six wells were in various stages of completion, and the Company had four rigs running.  The Company added its fifth rig in early July.  As of August 4, 2015, the Company had completed nine additional wells since the end of the second quarter.

Daily net production in the Cleveland was 18.0 MBoe/d in the second quarter of 2015, down 5% from the first quarter of 2015 and up 7% from the second quarter of 2014.  To date, the Company has spud 33 of the thirty-three stage open-hole wells, 25 of which have been completed and placed on production.  Production results for the 33 stage wells continue to reflect the uplifted oil production expectations which were observed during the Company’s completion optimization work in 2014.

The Company’s target well cost of $2.6 million was achieved during the second quarter, approximately two months ahead of expectations.  Drilling efficiencies and cost reductions have persisted as rigs have been added over recent months.

Capital Expenditures

During the second quarter of 2015, the Company spent $45.5 million, of which $40.5 million was related to drilling and completing wells, representing 89% of total capital expenditures in the quarter.  Quarterly spending continues to reflect budgeted expectations with minimal increases arising from non-operating interest owners electing not to participate in the drilling of wells.  The Company had anticipated the potential for working interest capture in its 2015 budget as the initial budget projected an average working interest for wells to be drilled of approximately 80%, which was higher than the Company’s average working interest of 70% owned as of the Company’s 2014 year-end reserve report.  Through the first six months of 2015, the actual average working interest of the wells spud was 92%.  Based upon the current rate of additional working interest capture, the Company is updating its estimated average working interest per well for 2015 to 90% to 95% versus the previously budgeted 80%.

Through this year’s forecasted average working interest capture of 20% to 25% per drilled well, the Company expects to add the equivalent of between 15 and 18 net locations to its producing well count with minimal cost.  This working interest increase achieves the goal of higher rig utilization and net location capture through continued drilling activity.

Specific to the second half of 2015, the Company is increasing the estimated average working interest per well from the budgeted 80% to between 90% and 95%.  This is expected to result in average incremental capital per rig line of approximately $3 million during the second half of 2015, or an increase in total drilling and completion expenditures of approximately $15 million.  The Company also has allocated additional capital for leasing during the third and fourth quarter, which together with working interest capture, results in total expected capital expenditures for the full year of approximately $240 million.

2015 Capital Expenditure Summary ($mm)

Liquidity and Hedging

As of June 30, 2015, the Company had undrawn credit facility availability of $462.5 million and approximately $23 million in cash.

The Company continued to add hedges during the second quarter of 2015, with the mark-to-market value of its hedge book exceeding $220 million as of late July.  The Company has hedged over 85% of its estimated oil and natural gas production through 2016 at an average price just below $85 per barrel and $4.50 per Mcf.  The Company’s estimated natural gas liquids production for the third and fourth quarter of 2015 is approximately 80% hedged at an average per

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, however, we may modify our definition of EBITDAX in the future.  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 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.  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 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 - and certain unusual or non-recurring items.  We believe adjusted net income 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, this measure is 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.  Our computations of adjusted net income may not be comparable to other similarly titled measures of other companies.  The following tables provide 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.
