MANAGEMENT COMMENTS

Tony Sanchez, III, Chief Executive Officer of Sanchez Energy, commented:  “Better well performance and efficiency gains continue to drive our 2015 operating results.  In the third quarter 2015, we achieved average daily production of approximately 52,844 BOE/D, well in excess of the top end of our production guidance, while continuing to reduce well costs. At Catarina, our average drilling and completion costs were $4.1 million per well during the third quarter 2015.  Of note, our South-Central Catarina wells have exceeded expectations, with average 30-day rates greater than 1,300 BOE/D and estimated ultimate recoveries tracking to nearly double the 600-700 MBOE Western Catarina type curve.”

“To date, a total of 41 wells have been drilled toward the Company’s 50 well annual drilling commitment at Catarina for the period July 2015 to June 2016.  With our two rig drilling program and new drilling efficiencies, we are currently averaging nine days spud to total depth at Catarina. As a result, the Company expects to nearly fulfill its current drilling commitment by year-end 2015. This would provide us with significant discretion to manage the capital needed to meet all drilling obligations through the first half of 2016, which would greatly improve our financial flexibility as we head into next year.”

“Further improving our financial flexibility, we have added significant liquidity with the Western Catarina Midstream divestiture, which closed in October 2015. As a result of the transaction, the Company maintained pro forma liquidity of approximately $842 million at the end of last quarter. Subsequent to the quarter, we also entered into joint ventures with a midstream partner, which we expect will enhance our marketing capability at Catarina through the construction and operation of a cryogenic gas processing plant and associated gathering pipeline.  We anticipate these joint ventures will allow us to achieve better liquids yields and lower processing fees, resulting in lower operating costs, higher net-backs, and greater price realization on our natural gas liquids revenue stream. The joint ventures are also expected to improve our access to end markets, including the developing Mexico and global LNG markets and provide opportunities to increase revenue through utilization of the new midstream system to transport and process third-party volumes.”

“As a result of our drilling and completion efficiency gains and cost reductions, today we reiterate our preliminary 2016 upstream capital spending guidance of $250 million to $300 million. Our 2016 capital budget is expected to maintain production consistent with 2015 levels and, based on the continuous improvements achieved in our well results, may lead to some moderate year-over-year growth. In addition, we currently forecast that the Company will make approximately $115 million in midstream capital investments associated with the joint ventures over the next 12 to 18 months.”

OPERATIONS UPDATE

The Company’s Eagle Ford development plan remains primarily focused on Catarina, where the Company plans to average two gross (two net) rigs for the remainder of 2015. In the third quarter 2015, the Company brought 27 gross (26.5 net) operated wells online.

At Catarina, third quarter 2015 development was focused primarily in Western Catarina, with a portion of the development focused on continued delineation of the South-Central area of the ranch.  Well results in Eastern Catarina have continued to exhibit a flat decline profile and are now tracking estimated ultimate recoveries (“EURs”) approaching the 600-700 MBOE type curve designated for Western Catarina.  In South-Central Catarina, well results have continued to trend above expectations and are currently tracking EURs of approximately 1,200 MBOE, nearly double the Western Catarina type curve.

Well costs in the third quarter 2015 averaged approximately $4.1 million, and are continuing to trend down with recent pad averages coming in below $4.0 million.  These reductions have come as a result of efficiency improvements and have been realized without modification to well design.

At Cotulla, the Company brought online six wells during the third quarter 2015 that are currently in the early stages of flow back.  Well costs, inclusive of a forecast for initial lift, averaged $3.7 million per well.  This area of the Eagle Ford continues be a high-rate of return development opportunity in the context of future capital programs, as the majority of the Company’s acreage is currently held by production.

As of September 30, 2015, the Company had 592 gross (476 net) producing wells with 30 gross (27 net) wells in various stages of completion, as detailed in the following table.

PRODUCTION VOLUMES, AVERAGE SALES PRICES, AND OPERATING COSTS PER BOE

The Company’s mix of hydrocarbon production during the third quarter 2015 consisted of approximately 34% crude oil, 31% natural gas liquids, and 35% natural gas.  By asset area, Catarina, Marquis, Cotulla, Palmetto/Other comprised approximately 77%, 8%, 12%, and 3%, respectively, of the Company’s total third quarter 2015 production volumes.

Revenue for the three months ended September 30, 2015 totaled $114.5 million, a decrease of 45% over the same period a year ago, due to a 45% decrease in the average sales price per BOE, inclusive of realized hedge gains, over that period.  The effect of the decrease in commodity prices was partially offset by higher production due to well performance and efficiency gains at Catarina.

Production, average sales prices, and operating costs and expenses per BOE for the third quarter 2015 are summarized in the table that follows:

(1) Excludes stock-based compensation of $0.07 and $0 per BOE for the three months ended September 30, 2015 and 2014, respectively, and $1.15 and $3.64 per BOE for the nine months ended September 30, 2015 and 2014, respectively.
(2) Excludes acquisition costs included in G&A of $0.26 and $0.25 per BOE for the three and nine months ended September 30, 2014, respectively.

Third quarter 2015 results and fourth quarter 2015 guidance are summarized in the table that follows:

The Company reported Adjusted EBITDA of $94.3 million and Adjusted Net Income (Loss) of ($28.4) million for the third quarter 2015, which compares to Adjusted Net Income of $12.8 million reported in the third quarter 2014.  Adjusted EBITDA and Adjusted Net Income (Loss) are non-GAAP financial measures defined in the tables included with today’s news release.

RECONCILIATION OF NON-GAAP MEASURES

(unaudited)

Adjusted EBITDA is used as a supplemental financial measure by our management and by external users of our financial statements, such as investors, commercial banks and others, to assess our operating performance as compared to that of other companies in our industry, without regard to financing methods, capital structure or historical costs basis.  It is also used to assess our ability to incur and service debt and fund capital expenditures.

We define Adjusted EBITDA as net income (loss):

Plus:

·              Interest expense, including net losses (gains) on interest rate derivative contracts;

·              Net losses (gains) on commodity derivative contracts;

·              Net settlements received (paid) on commodity derivative contracts;

·              Depreciation, depletion, amortization and accretion expense;

·              Stock-based compensation expense;

·              Acquisition costs included in general and administrative expense;

·              Income tax expense (benefit);

·              Loss (gain) on sale of oil and natural gas properties;

·              Impairment of oil and natural gas properties; and

·              Other non-recurring items that we deem appropriate.

Less:

·              Premiums on commodity derivative contracts;

·              Interest income; and

·              Other non-recurring items that we deem appropriate.

We present Adjusted Net Income (Loss) attributable to common stockholders (“Adjusted Net Income (Loss)”) in addition to our reported net income (loss) in accordance with U.S. GAAP. This information is provided because management believes exclusion of the impact of the items included in our definition of Adjusted Net Income (Loss) below will help investors compare results between periods, identify operating trends that could otherwise be masked by these items and to highlight the impact that commodity price volatility has on our results. We define Adjusted Net Income (Loss) as net income (loss):

Plus:

·                  Non-cash preferred stock dividends associated with conversion;

·                  Net losses (gains) on commodity derivative contracts;

·                  Net settlements received (paid) on commodity derivative contracts;

·                  Stock-based compensation expense;

·                  Acquisition costs included in general and administrative expense;

·                  Impairment of oil and natural gas properties;

·                  Other non-recurring items that we deem appropriate; and

·                  Tax impact of adjustments to net income (loss).

Less:

·                  Premiums on commodity derivative contracts;

·                  Preferred stock dividends; and

·                  Other non-recurring items that we deem appropriate.

(1)     The tax impact is computed by utilizing the Company’s effective tax rate on the adjustments to reconcile net income to Adjusted Net Income.

(2)     The Company’s restricted shares of common stock are participating securities.

(3)     The three and nine months ended September 30, 2015 excludes 597,910 and 2,663,010 shares of weighted average restricted stock and 12,530,695 shares of common stock resulting from an assumed conversion of the Company’s Series A Convertible Perpetual Preferred Stock and Series B Convertible Perpetual Preferred Stock from the calculation of the denominator for diluted earnings per common share as these shares were anti-dilutive.

(4)     The three and nine months ended September 30, 2014 excludes 863,412 and 1,290,637 shares of weighted average restricted stock and 12,607,521 and 13,863,738 shares of common stock resulting from an assumed conversion of the Company’s Series A Convertible Perpetual Preferred Stock and Series B Convertible Perpetual Preferred Stock from the calculation of the denominator for diluted earnings per common share as these shares were anti-dilutive.
