2015 Proved Reserves

The Company’s estimated proved reserves as of December 31, 2015 were approximately 146.8 million barrels of oil equivalent (MMBoe). Year-end 2015 estimated proved reserves were 82% oil, 9% NGLs and 9% natural gas on an equivalent basis. Of total estimated proved reserves, 83% were in the Williston Basin, 15% were in the East Texas Eagle Ford (“El Halcón”) and 2% were in other areas. Year-end 2015 estimated proved reserves were approximately 95% Company-operated and 56% proved developed.

Halcón’s estimated proved reserves at December 31, 2015 were prepared by the independent reserve engineering firm Netherland, Sewell and Associates, Inc. in accordance with Securities and Exchange Commission guidelines using NYMEX prices of $50.28 per barrel for oil and $2.59 per million British Thermal Unit for natural gas, before adjustments for energy content, quality, midstream fees and basis differentials.

Operations Update

The Company is currently running 2 operated rigs in the Fort Berthold area of the Williston Basin but will scale down to 1 rig operating in the Fort Berthold area by the end of March 2016.

2

Although Halcón currently has 1 operated rig running in its El Halcón area, the Company does not plan to run any rigs in this area after March of 2016 until oil prices improve.  The Company currently has 13 wells in the Bakken and 2 wells in the East Texas Eagle Ford being completed or waiting on completion.

Bakken/Three Forks

The Company operated an average of 2 rigs and 2.2 rigs in the Williston Basin during the fourth quarter and full year 2015, respectively.

Halcón spudded 10 wells and put 5 wells online in the Williston Basin during the three months ended December 31, 2015. The Company also participated in 27 non-operated wells during the quarter with an average working interest of approximately 1.4%. Production averaged 29,721 Boe/d during the fourth quarter of 2015 in the Williston Basin.

For the full year 2015, Halcón spudded 39 wells and put 39 wells online in the Williston Basin. The Company also participated in 100 non-operated wells during the year with an average working interest of approximately 1.7%.

Halcón plans to concentrate its efforts in its highest return area (Fort Berthold Indian Reservation, or FBIR) in 2016 and anticipates spending approximately 80% to 85% of its total drilling and completions budget in the FBIR area of the Williston Basin.

During 2015, the Company put 33 operated wells online in the FBIR with an average EUR of 800 MBoe (25 Middle Bakken, 8 Three Forks).  In 2016, Halcón expects wells put online to have an average EUR of approximately 900 MBoe as it focuses drilling on the best parts of its acreage position.

In 2015, the Company put 6 operated Middle Bakken wells online in Williams County with an average EUR of 553 MBoe.  Although Halcón does not plan to drill in Williams County in 2016, any wells drilled in this area would generate a positive return at current strip prices based on 2015 EURs.

The Company continues to improve on well costs with current FBIR AFEs at $6.2 million and Williams County AFEs at $5.7 million.

Halcón currently has working interests in approximately 123,000 net acres prospective for the Bakken and Three Forks formations in the Williston Basin, substantially all of which are held by production (HBP). The Company plans to operate an average of 1 rig and spud 15 to 20 gross operated wells in 2016 with an average working interest of approximately 60%. Halcón also expects to participate in 50 to 65 gross non-operated wells in 2016 with an average working interest of approximately 1.5%.

(1)         Represents charges related to the write-off of debt issuance costs associated with decreases in the Company’s borrowing base under its senior revolving credit facility.

(2)         For the 2015 columns, this represents the tax impact using an estimated tax rate of 0.0% due to the Company maintaining a full valuation allowance. For the 2014 columns, this represents tax impact using an estimated tax rate of 37.04%. These columns include a $(74.4) million (quarter-to-date) and $(102.1) million (year-to-date) adjustment for the change in valuation allowance.

(3)         Net income (loss) and earnings per share excluding selected items and cash flow from operations before changes in working capital adjusted for selected items are non-GAAP measures. These financial measures are presented based on management’s belief that they will enable a user of the financial information to understand the impact of these items on reported results. Additionally, this presentation provides a beneficial comparison to similarly adjusted measurements of prior periods.  These financial measures are not measures of financial performance under GAAP and should not be considered as an alternative to net income, earnings per share and cash flow from operations, as defined by GAAP.  These financial measures may not be comparable to similarly named non-GAAP financial measures that other companies may use and may not be useful in comparing the performance of those companies to Halcón’s performance.

(4)         The impact of selected items for the three months ended and year ended December 31, 2015 was calculated based upon weighted average diluted shares of 144.8 million and 131.8 million, respectively, due to the net income available to common stockholders, excluding selected items.
