MANAGEMENT COMMENTS

“We are off to a strong start in 2016,” said Tony Sanchez, III, Chief Executive Officer of Sanchez Energy. “As previously reported, we achieved excellent production results in the first quarter 2016, exceeding the high end of our guidance by over 8.5%.  Process improvements and efficiency gains continue to drive our performance, with several wells coming in at a cost of approximately $3.0 million.  This combination of lower costs and strong production has allowed us to achieve positive returns on our capital program, even in today’s challenging commodity price environment, which provides us with a key competitive advantage in responding to current industry conditions.”

“During the first quarter 2016, our development focus remained on Catarina and further delineation of the South-Central region of the lease.  Development results in this area continue to meet or exceed our expectations, with 11 additional wells brought on-line in South-Central Catarina during the quarter.  The 15 total wells brought on-line as of March 31, 2016 in South-Central Catarina have averaged 30-day production rates of greater than 1,300 Boe/d.  Since March 31, 2016, we have also brought the E15 pad on-line, which is a 5-well pad that appraises the area between Western and South-Central Catarina.  Initial production and pressure results from the E15 pad exceeded expectations and are in line with recent results in South-Central Catarina.  The extension of the fairway between our two most productive regions of Catarina expands an already significant growth of inventory in South-Central Catarina.”

“As a result of design and process improvements, we are currently averaging 8 days spud to total depth at Catarina and 6 days at Cotulla. As a testament to the continued optimization, one of our most recent wells was drilled with a spud to total depth time of 4.35 days at a cost of $66 per foot including production casing.  In addition to having already met our drilling commitments at Catarina for the period July 2015 through June 2016, as of March 31, 2016, we have banked 13 wells toward our 50 well annual drilling commitment for the period July 2016 through June 2017.  We anticipate that our two rig drilling program at Catarina will drop to one rig by mid-year 2016, at which time we anticipate a bank of approximately 20 wells toward our next annual drilling commitment, which runs from July 2016 through June 2017.  This provides us with considerable financial flexibility as we execute our 2016 program and plan for future development and other opportunities that may emerge as a result of distress in the industry.”

“With respect to our midstream strategy, the Carnero Pipeline, constructed by the Targa joint venture, went in-service in March 2016 and now transports the majority of our Catarina gas volumes.  The joint venture continues construction of a new cryogenic natural gas processing plant in La Salle County, Texas.  Once complete, the project is expected to provide a path to improved yields, lower processing fees, and significant marketing benefits to Sanchez Energy.”

“Based on the strong showing in the first quarter 2016, we reiterate our 2016 upstream capital spending guidance of $200 million to $250 million.  Our 2016 capital budget is expected to maintain production consistent with 2015 levels, with approximately 70% of the capital expected to be incurred in the first half of the year.”

OPERATIONS UPDATE

The Company’s Eagle Ford development plan remains primarily focused on Catarina, where the Company is currently running two rigs and expects to reduce activity to one rig by the end of the second quarter 2016.  First quarter 2016 development activity was primarily focused in South-Central Catarina, where the Company has realized some of the best production results on the lease.  South-Central Catarina well results continue to trend above expectations and are currently tracking estimated ultimate recoveries (“EURs”) of approximately 1,100 thousand barrels of oil equivalent (“MBoe”).  The Company has met its 50 well annual drilling commitment at Catarina for the period July 2015 through June 2016 and, as of March 31, 2016, has banked 13 wells toward the 50 well annual drilling commitment for the period July 2016 through June 2017.

Drilling and completion costs in the first quarter 2016 averaged approximately $3.3 million per well at Catarina and $3.4 million per well at Cotulla, with the Company’s best wells coming in at approximately $3.0 million per well in both areas.  Nearly all of the Company’s recent well cost reductions are attributable to process and design improvements, which have resulted in reductions in drill time.  The Company’s well cost reductions are expected to be sustainable, even in a rising commodity price environment.

As of March 31, 2016, the Company had 640 gross (522 net) producing wells with 17 gross (15.5 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 production mix during the first quarter 2016 consisted of approximately 32% oil, 33% natural gas liquids (“NGLs”), and 35% natural gas.  By asset area, Catarina, Marquis, Cotulla, and Palmetto/Other comprised approximately 81%, 6%, 10%, and 3%, respectively, of the Company’s total first quarter 2016 production volumes.

Revenue, inclusive of realized hedge gains, for the three months ended March 31, 2016 totaled approximately $133 million, a decrease of just 5% when compared to the same period a year ago.  The effect of the decrease in commodity prices was partially offset by higher production due to better well performance and efficiency gains across the portfolio.

Production, average sales prices, and operating costs and expenses per Boe for the first quarter 2016 are summarized in the tables that follow:

FINANCIAL RESULTS

The Company reported Adjusted EBITDA of $64.6 million and Adjusted Net Income (Loss) of ($17.6) million for the first quarter 2016, which compares to Adjusted Net Income (Loss) of $(55.2) million reported in the first quarter 2015.  Adjusted EBITDA and Adjusted Net Income (Loss) are non-GAAP financial measures defined in the tables included with today’s news release.

HEDGING UPDATE

In April 2016, the Company entered into swaps to hedge 1,000 Bbl/d of oil in 2017 at a fixed price of $50.00/Bbl and 10,000 MMBtu/d of natural gas in 2018 at a fixed price of $3.00/MMBtu.  The Company’s counterparty on the swaps has the right, under certain circumstances, to expand the hedges to cover an additional 1,000 Bbl/d of oil in 2017 and an additional 10,000 MMBtu/d of natural gas in 2018 at the same fixed prices.  In May 2016, the Company entered into an additional swap to hedge 10,000 MMBtu/d of natural gas in 2018 at a fixed price of $3.00/MMBtu. This brings the Company’s current total hedged position to 18,000 Bbls/d of oil and 99,154 MMbtu/d of natural gas in 2016, 1,000 to 2,000 Bbls/d of oil and 76,562 MMbtu/d of natural gas in 2017, and 20,000 to 30,000 MMbtu/d of natural gas in 2018.

LIQUIDITY AND CREDIT FACILITY

The Company had liquidity of approximately $662 million as of March 31, 2016, which consisted of $362 million in cash and cash equivalents and an undrawn bank credit facility with an elected commitment amount of $300 million and a borrowing base of $350 million.  The Company’s elected commitment amount on the bank credit facility is expected to remain at $300 million until the next semi-annual redetermination of the borrowing base by the lenders, which is anticipated in the fourth quarter 2016.

SHARE COUNT

As of March 31, 2016, the Company had 64.3 million total common shares outstanding.  Assuming all Series A Convertible Perpetual Preferred Stock and Series B Convertible Perpetual Preferred Stock were converted, total outstanding common shares as of March 31, 2016 would have been 76.8 million.  For the three months ended March 31, 2016, the weighted average number of unrestricted common shares used to calculate net loss attributable to common stockholders and adjusted net income (loss) per common share, basic and diluted, which are determined in accordance with GAAP, was 58.1 million.
