·            Production of 1,691 MBOE (18,784 BOE/D), pre-released April 28, 2014

MANAGEMENT COMMENTS

Tony Sanchez, III, President and Chief Executive Officer of Sanchez Energy, commented: “The first quarter of 2014 was marked by a more than three-fold rise in both production and earnings as a result of our full-scale development mode across our Eagle Ford areas using multi-well pads and zipper-fracs whenever possible. We added 172 gross new wells to our inventory year over year thanks in large part to the significant manufacturing efficiency and well cost improvements achieved through our proprietary systems and drilling processes. These efficiencies have contributed to overall total well costs reduction of 30% across all our Eagle Ford operations. Specifically, in our Wycross area, we drilled the final well of a three-well pad with drilling costs at $3 million or less per well and expect to bring these wells online in June.  Completion costs for these wells are expected to be approximately $4.5 million, for a total of $7.5 million, a completed well cost that we believe drives top returns in the play.”

“Moving forward, we will maintain our unrelenting focus on reducing well costs, thereby enhancing the expected return across all of our acreage positions. We have recently spud wells in our Wright Ranch and Talbutt Trust areas of Cotulla and plan to evaluate other positions as our cost structure continues to improve. In our Five Mile Creek area of Marquis, we have drilled the last well of a four-well pad and will begin completing the four wells soon with expected first oil production in June.”

OPERATIONS UPDATE

As detailed in the table below, Sanchez Energy currently has six gross rigs (five operated and one non-operated rig) running across its Eagle Ford areas with 216 gross producing wells and 19 gross wells in various stages of completion. In addition, one rig is currently running in the TMS in which Sanchez Energy has a non-operated interest.

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

Sanchez Energy’s mix of hydrocarbon production during the first quarter of 2014 consisted of approximately 72% crude oil, 13% natural gas and 15% natural gas liquids.  The percentage of oil in the Company’s first quarter production volumes was unusually low due to the preponderance of well completions occurring in areas with higher percentages of natural gas and NGL’s in the production stream. Late in the first quarter both drilling and completion activities shifted back to a traditional pattern with expectations of future oil production volumes returning to the traditional approximate 75% level.

Revenue for the three months ended March 31, 2014 totaled $134.6 million, an increase of 334% over the same period a year ago, due to the addition of 172 gross new wells since the first quarter 2013, including 103 gross wells from ongoing operations and 69 gross wells from the acquisition of new properties.

Production, average sales prices and operating costs and expenses per BOE for the first quarter 2014 as well as guidance for the second quarter and full year of 2014 are summarized below:

(1) Excludes stock-based compensation of $5.88 and $8.83 per BOE for the three months ended March 31, 2014 and 2013, respectively. Excludes acquisition costs included in G&A of $0 and $1.74 per BOE for the three months ended March 31, 2014 and 2013, respectively.

Capital expenditures, before estimated accruals, for the first quarter 2014 were approximately $103 million, and capital expenditures incurred during the first quarter, including accruals, was approximately $152 million.

HEDGING UPDATE

Subsequent to quarter end, Sanchez Energy entered into two crude oil and two natural gas enhanced swap contracts. The two crude oil enhanced swaps have a contract period from January 1, 2015 through December 31, 2015 for 1,000 barrels per day, using NYMEX WTI as the pricing index. Both crude oil enhanced swaps have a strike price of $91.46 per barrel with a put option at $75.00 per barrel. The two natural gas enhanced swaps have a contract period from January 1, 2015 through December 31, 2015 and use NYMEX NG as the pricing index. The first

natural gas enhanced swap is for 6,000 MMBtus per day and has a strike price of $4.44 per MMBtu with a put option at $3.75 per MMBtu.  The second natural gas enhanced swap is for 2,000 MMBtus per day and has a strike price of $4.50 per MMBtu with a floor price of $3.75 per MMBtu.

Currently, Sanchez Energy has approximately 3.5 million barrels of anticipated crude production and 3.3 Bcf of gas production for 2014 hedged, or approximately 4 million BOE, which represents about 50% of its anticipated total 2014 production at the mid-point of its guidance range. A schedule of all current hedges for 2014 and 2015 production is included herein.

RECONCILIATION OF NON-GAAP MEASURES

(unaudited)

I.                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 derivatives;

·                  Net settlements received (paid) on commodity derivatives;

·                  Premiums (paid) on commodity derivative contracts;

·                  Depreciation, depletion, amortization, and accretion;

·                  Stock-based compensation expense;

·                  Acquisition costs included in general and administrative;

·                  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:

·                  Interest income; and

·                  Other non-recurring items that we deem appropriate.

The following table presents a reconciliation of our net income (loss) to Adjusted EBITDA (in thousands):

Our Adjusted EBITDA should not be considered an alternative to net income (loss), operating income (loss), cash flow provided by or used in operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP.  Our Adjusted EBITDA may not be comparable to similarly titled measures of another company because all companies may not calculate Adjusted EBITDA in the same manner.

II.           We present Adjusted Net Income attributable to common stockholders (“Adjusted Net Income”) in addition to our reported net income (loss) in accordance with GAAP. This information is provided because management believes exclusion of the impact of our unrealized derivatives not accounted for as cash flow hedges and stock-based compensation expense will help investors compare results between periods and 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 as net income (loss):

Plus:

·                  Non-cash preferred stock dividends associated with conversion;

·                  Net losses (gains) on commodity derivatives;

·                  Net settlements received (paid) on commodity derivatives;

·                  Premiums (paid) on commodity derivative contracts;

·                  Stock-based compensation expense;

·                  Acquisition costs included in general and administrative;

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

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

Less:

·                  Preferred stock dividends; and

·                  Other non-recurring items that we deem appropriate.

The following table presents a reconciliation of our net income (loss) to Adjusted Net Income (in thousands, except per share data):

(1)   The three months ended March 31, 2014 excludes 1,115,834 shares of weighted average restricted stock and 15,764,879 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 Adjusted net income per common share as these shares were anti-dilutive.

(2)   The three months ended March 31, 2013 excludes 579,019 shares of weighted average restricted stock and 7,422,400 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 Adjusted net income per common share as these shares were anti-dilutive.

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

Adjusted Net Income is not intended to represent cash flows for the period, nor is it presented as a substitute for net income (loss), operating income (loss), cash flows provided by or used in operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP.
