Sanchez Energy Announces Fourth Quarter and

Full-Year 2016 Financial Results and Operations Update

HOUSTON--(GLOBE NEWSWIRE)--Feb. 22, 2017--Sanchez Energy Corporation (NYSE: SN), today announced operating and financial results for the fourth quarter and full-year 2016.  Highlights include:

MANAGEMENT COMMENTS

“Starting in early 2016, we made the strategic decision to maintain high liquidity levels while operationally concentrating our efforts in the Western Eagle Ford, an area where we see considerable growth potential and impressive returns” said Tony Sanchez, III, Chief Executive Officer of Sanchez Energy. “We achieved excellent operating results in 2016 with average production of 53,350 Boe/d for the full year. The combination of low cost drilling operations and improving well performance has allowed us to unlock considerable value in our Western Eagle Ford position. This is evident in our ability to dramatically reduce capital spending in 2016, compared to 2015, and still execute our appraisal and development plans to maintain production levels and significantly increase proved reserves.  With the development and appraisal drilling over the last twelve months, we increased year-end reserves by over 55%, excluding acquisitions and divestitures, and generated an approximate 430% reserve replacement ratio.”    

“We further enhanced our strong liquidity position through a series of strategic divestitures in 2016, including multiple transactions that stemmed from our relationship with Sanchez Production Partners, LP (“SPP”). The strong liquidity position provided us the financial flexibility to expand our footprint in the Western Eagle Ford, solidifying our position as one of the largest operators in the basin.  Over the last twelve months, we actively leased acreage to the north and south of Catarina, resulting in the addition of 65,000 acres in the Maverick area, located in the oil window of the Western Eagle Ford, and 45,000 acres in the Javelina area, located in the dry gas window of the Western Eagle Ford.  In January 2017, we announced the Comanche Transaction which includes approximately 33,500 Boe/d of net production at the time of announcement and over 4,000 gross identified Eagle Ford drilling locations.  The 132 (gross) drilled but uncompleted wells (“DUCs”) that will be acquired with the Comanche assets provide an opportunity to quickly ramp production and dramatically increase cash flow in the near term.  With rates of return expected to exceed 100 percent, we see this as an excellent use of capital in 2017 that we believe will lead to a significantly stronger balance sheet over a relatively short period of time.

“As we begin our 2017 drilling plans, we remain focused on the Catarina and Maverick areas of our asset base, along with the integration of the Comanche assets. New step out wells in South-Central and Northwestern Catarina have provided further definition on the extent of their fairways. Recent wells, along with a pilot-well drilled in North-Central Catarina, have confirmed the Upper

Eagle Ford is extensive across the western side of Catarina.  During 2017, we anticipate bringing on production from approximately 32 net wells in South-Central Catarina, approximately 11 net wells with stacked development planned in Western Catarina, in addition to other drilling and completions operations in Catarina.  At Maverick, we intend to bring approximately 35 net wells online around Hauser and our other high rate of return leases.” 

OPERATIONS UPDATE

The Company is currently running 2 rigs in Catarina and 2 rig in Maverick. As of Dec. 31, 2016, the Company had completed its 50 well annual drilling commitment at Catarina for the period from July 2016 through June 2017.  Upon closing of the Comanche Transaction, the Company expects to ramp up drilling activity on Comanche and exit the year running 5 rigs on the assets.

Drilling and completion costs in the fourth quarter 2016 averaged approximately $3.2 million per well at both Catarina and Maverick, which includes testing of larger completions and longer laterals during the quarter.  For the full-year 2016, average drilling and completion costs at Catarina and Maverick were approximately $3.0 million per well.

As of Dec. 31, 2016, the Company had 611 gross (473 net) producing wells with 25 gross (22 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 fourth quarter 2016 consisted of approximately 34 percent oil, 29 percent NGL, and 37 percent natural gas.  By asset area, Catarina, Marquis, Maverick, and Palmetto/TMS/Other comprised approximately 82 percent, 4 percent, 12 percent, and 2 percent, respectively, of the Company’s total fourth quarter 2016 production volumes.

Revenues of approximately $126 million during the fourth quarter 2016 were up 15% compared to the fourth quarter 2015.  Hedge settlement gains totaled $20 million for the fourth quarter 2016.   Commodity price realizations during the fourth quarter 2016, including the impact of derivative instrument settlements, were $56.88 per barrel of oil, $18.81 per barrel of NGL and $3.25 per thousand cubic feet (“Mcf”) of natural gas. 

Production, average sales prices, and operating costs and expenses per barrel of oil equivalent (“Boe”) for the fourth quarter and full-year 2016 are summarized in the table that follows:

CAPITAL EXPENDITURES

Capital outflows related to capital expenditures incurred during the full-year 2016 totaled approximately $349.8 million.  The Company spent approximately 75.7 percent of its capital expenditures on drilling, completion, infrastructure, and G&G activities, 13.9 percent related to

leasing and business development, and 10.4 percent related to our midstream joint ventures that were subsequently sold.

SHARE COUNT

As of Dec. 31, 2016, the Company had 66.2 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 Dec. 31, 2016 would have been 78.7 million.  For the three months ended Dec. 31, 2016, the weighted average number of unrestricted common shares used to calculate net loss attributable to common

Non-GAAP Reconciliation – Adjusted EBITDA

Adjusted EBITDA is a non‑GAAP financial measure that 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.  Our Adjusted EBITDA should not be considered an alternative to net income (loss), operating income (loss), cash flows provided by (used in) operating activities or any other measure of financial performance or liquidity presented in accordance with U.S. 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.  The following table presents a reconciliation of our net loss to Adjusted EBITDA (in thousands).
