NEWS RELEASE

Halcón Resources Announces Fourth Quarter 2018 Results and Provides an Update on Operations and Other Activities

DENVER, COLORADO — March 12, 2019 — Halcón Resources Corporation (NYSE:HK) (“Halcón” or the “Company”) today announced its fourth quarter 2018 results and provided an update on recent well results, operations and other matters.

Net production for the three months ended December 31, 2018 averaged 17,196 barrels of oil equivalent per day (Boe/d).  Production was comprised of 69% oil, 14% natural gas liquids (NGLs) and 17% natural gas for the quarter.  Third party sour gas takeaway constraints in Halcón’s Monument Draw area resulted in significantly lower gas and NGL volumes than expected and also had a negative impact on oil production.  The Company expects to resolve this take-away issue when its sour gas treatment plant is completed later this month.

Halcón generated total revenues of $60.3 million for the fourth quarter of 2018.  The Company reported net income available to common stockholders of $146.7 million or net income per basic and diluted share of $0.93 for the fourth quarter of 2018.  After adjusting for selected items (see Selected Item Review and Reconciliation table for additional information), the Company generated a net loss of $(13.9) million, or $(0.09) per diluted share for the fourth quarter of 2018.  Adjusted EBITDA (see EBITDA Reconciliation table for additional information) totaled $24.5 million for the fourth quarter of 2018.

Excluding the impact of hedges, Halcón realized 83% of the average NYMEX oil price, 34% of the average NYMEX oil price for NGLs and 29% of the average NYMEX natural gas price (see Selected Operating Data table for additional information) during the fourth quarter of 2018.  The Company’s realized gas price was lower than previous periods primarily as a result of low WAHA prices in the quarter.  Realized hedge losses totaled approximately $2.6 million during the fourth quarter.

Total operating costs per unit, after adjusting for selected items (see Selected Operating Data table for additional information), were $21.14 per Boe for the fourth quarter of 2018, compared to $18.20 per Boe for the third quarter of 2018.  This increase in per unit total operating costs was primarily driven by increased water disposal costs associated with the Company’s previously announced water infrastructure divestiture in addition to higher water disposal costs related to recently completed wells in West Quito Draw.   The higher costs were also partially attributable to a short-term sour gas takeaway agreement in Monument Draw to alleviate takeaway constraints.

Liquidity and Capital Spending

As of December 31, 2018, Halcón’s liquidity was $321 million consisting of $47 million in cash on hand plus an undrawn $275 million revolving credit facility less letters of credit outstanding.

During the fourth quarter of 2018, Halcón incurred capital costs of approximately $94 million on drilling and completions and $41 million on infrastructure, seismic and other.

Hedging Update

As of March 12, 2019, Halcón has ~12,835 barrels per day (Bbl/d) of oil hedged for 2019 at an average price of $56.95 per barrel.  For 2020, the Company has ~5,695 Bbl/d of oil hedged at an average price of $58.04 per barrel.  Halcón also has Midland vs. Cushing basis differential swaps in place for ~8,633 Bbl/d for 2019 at an average swap price of -$4.09 per barrel.  The Company also has Magellen East Houston vs. Cushing basis swaps in place for ~5,000 Bbl/d in the fourth quarter of 2019 at +$3.72 per barrel and ~9,000 Bbl/d in 2020 at +$2.95 per barrel.

As of March 12, 2019, Halcón had 24,000 MMBtu/d of natural gas hedged in 2019 at an average price of $2.81 per MMBtu.  The Company had WAHA vs. NYMEX basis differential swaps in place for 25,500 MMBtu/d for 2019 at an average swap price of -$1.18 per MMBtu/d.

As of March 12, 2019, Halcón had ~3,815 barrels per day of natural gas liquids hedged for 2019 at $29.34 per barrel.

Chairman’s Comments

Jim Christmas, Halcón’s Chairman of the Board commented “Although there have been significant recent changes in the executive leadership at Halcón, the Board is confident in the capabilities of the Halcón team going forward.  Halcón’s operations group is fully intact under the leadership of Jon Wright, Halcón’s Chief Operating Officer, and focused more than ever on delivering strong well results in a cost-efficient manner.

Going forward Halcón is laser-focused on cost control and capital efficiency.  The Company will continue to look for ways to improve profitability across all areas of the organization with an emphasis on ensuring we maximize returns while growing production.

The Board of Directors believes there is significant value in Halcón’s assets which is not being recognized by the market.  The Board plans to engage advisors to assist in a review of the Company’s financial and strategic options.

This engagement will include an assessment of value under various go-forward scenarios including a potential sale of select assets, M&A options and a scenario in which Halcón continues to develop and delineate its assets in the most capital efficient manner possible.  It will also include a review of alternative financing options to ensure Halcón has sufficient liquidity and financial flexibility going forward.  The engagement of advisors is an effort to ensure we fully investigate every possible option available to maximize value for our shareholders’ benefit.  We are excited about Halcón’s future prospects and look forward to executing on our efforts to improve shareholder value.”

Proved Reserve Update

Halcón’s estimated proved reserves as of December 31, 2018 increased 67% from last year to approximately 85.2 Mmboe, comprised of 59% oil, 20% NGL and 21% gas.  Proved developed reserves were approximately 39.9 Mmboe.  Halcón’s estimated proved reserves at December 31, 2018 were prepared by the independent reserve engineering firm Netherland Sewell & Associates, Inc. in accordance with Securities and Exchange Commission guidelines using an average West Texas Intermediate price of $65.56 per barrel for oil and an average Henry Hub Natural Gas spot price of $3.10 per Million British Thermal Units for natural gas, before adjustment for energy content, quality, midstream fees and basis differentials.

Operations Update

The Company recently dropped an operated rig and is planning to run two operated rigs for the remainder of 2019 focused on developing its Monument Draw and West Quito Draw areas of the Delaware Basin.  Halcón’s 2019 drilling plan is comprised of multi-well pad development with a focus on maximizing capital efficiency.  The Company’s most recent four wells in Monument Draw were drilled in record time and at much improved costs.

Halcón’s first two operated Wolfcamp horizontal wells in West Quito Draw, the Apres Vous 1H and Hornsilver 1H, were put online in early November and had peak 30-day IP rates of 1,656 Boe/d (43% oil) and 1,393 Boe/d (42% oil), respectively on restricted choke.  The 60-day peak IP rates for these wells were 1,549 and 1,341 Boe/d, respectively.  Both of these wells are located in the southern section of the Company’s West Quito Draw area and were completed with lateral lengths of approximately 9,650 feet each.  The Apres Vous targeted the lower Wolfcamp formation while the Hornsilver targeted the upper Wolfcamp formation.  After being online for more than 90 days, each of these wells continues to produce in excess of 1,000 Boe/d without artificial lift.  In the last several weeks Halcón has put five additional ~10,000 foot Wolfcamp wells online in West Quito Draw.  These wells are currently cleaning up after frac and have not yet reached peak IP rates.  Halcón expects to put four additional gross operated Wolfcamp wells online in West Quito Draw over the remainder of 2019.

3

After moving a rig out of Monument Draw for most of the second half of 2018, the Company recently started drilling in the area again with the start-up of its sour gas treatment plant planned for later this month.  At year-end 2018, Halcón had eight wells with surface and intermediate casing set awaiting lateral drilling and completion.  The Company plans to put four new wells online with ~5,000 to ~7,500 foot lateral lengths targeting the lower Wolfcamp by the end of April.  Halcón also plans to bring on-line the previously shut-in Sealy Ranch 7506H well in the next few weeks.  The Company plans to put an additional eight gross operated wells online in Monument Draw over the remainder of 2019.

Monument Draw Sour Gas Update

Halcón incurred approximately $20.1 million in non-recurring H2S treating costs in Monument Draw in the fourth quarter of 2018.  These costs were elevated when compared to expectations as the Company had an interruptible third party sour gas sales line that did not take as much gas as anticipated during the quarter.  As previously disclosed, Halcón has continued to incur these elevated non-recurring costs during the first quarter of 2019; however, the Company’s Valkyrie sour gas treatment plant, which is being constructed at Halcón’s central production facility in Monument Draw, is expected to be operational later this month.  The Company expects sour gas treating costs to be materially lower once this plant is operational.

2019 Guidance

Management Commentary

Jon C. Wright, Halcon’s Executive Vice President and COO commented “In 2017 and 2018, Halcón was focused on delineating and de-risking its acreage positions by drilling primarily single well pads and doing extensive R&D (i.e. shuttle logs, micro-seismic, etc.).  Our focus going forward is on maximizing well-level economics and corporate-level profitability.  We will only drill in what we believe are our best areas in an effort to maximize capital efficiency.  We have seen real improvement on recent drilling costs in Monument Draw where our most recent wells came in well below 2018 levels.  We expect West Quito well costs will also improve as we continue our development of that asset.

Unexpected high levels of H2S on Monument Draw wells resulted in our deferring drilling activity in that area for about six months, incurring very high gas treating costs and incurring additional capex to build out our H2S gathering and treating infrastructure.  Once our sour gas treating plant is operational later in March we will return to developing this premier acreage position.  The completion of this treating plant will further increase the value of our already valuable oil and gas infrastructure assets.

We are excited by the early production results of our initial wells drilled in West Quito Draw.  With the five put online recently in West Quito Draw and five more wells expected to be put online in Monument Draw in the near-term, we expect significant production growth in the second quarter of 2019.”

(1) For the 2017 column, this represents non-recurring charges in connection with the redetermination of the Company’s borrowing base under its senior revolving credit facility.

(2)  For the 2018 columns, this represents tax impact using an estimated tax rate of 21.0%. These columns include a $43.9 million (quarter-to-date) and $65.5 million (year-to-date) adjustment for the net change in valuation allowance and deferred tax asset. For the 2017 columns, this represents tax impact using an estimated tax rate of 0.0% due to the Company maintaining a full valuation allowance.

(3) Net income (loss) and earnings per share excluding selected items and cash flows from operations before changes in working capital adjusted for selected items are non-GAAP measures 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 flows 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)  For the year ended December 31, 2018, net income (loss) and earnings per share excluding selected items and cash flows from operations before changes in working capital include approximately $35.2 million of proceeds primarily related to hedge monetizations that occurred during the year.

(5) The impact of selected items for the three months ended December 31, 2018 and 2017 was calculated based upon weighted average diluted shares of 158.1 million and 148.5 million, respectively, due to the net loss available to common stockholders, excluding selected items.

The impact of selected items for the years ended December 31, 2018 and 2017 was calculated based upon weighted average diluted shares of 157.0 million and 132.8 million, respectively, due to the net loss available to common stockholders, excluding selected items.
