Item 3.01                   Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

On August 25, 2015, Halcón Resources Corporation (the “Company”) was notified by the New York Stock Exchange (the “NYSE”) that the average closing price of the Company’s common stock had fallen below $1.00 per share over a period of 30 consecutive trading days, which is the minimum average share price required by the NYSE under Section 802.01C of the NYSE Listed Company Manual. As of August 27, 2015, the 30 trading-day average closing price of the Company’s common stock was $0.96 per share.

The Company plans to notify the NYSE that it intends to cure the deficiency and to return to compliance with the NYSE continued listing requirement, and will submit a letter outlining the actions it intends to take to do so. The Company has six months following receipt of the notification to regain compliance with the minimum share price requirement, but may have additional time if shareholder approval is needed for any of its planned steps. The Company can regain compliance at any time during the six-month cure period if the Company’s common stock has a closing share price of at least $1.00 on the last trading day of any calendar month during the period and also has an average closing share price of at least $1.00 over the 30-trading day period ending on the last trading day of that month or on the last day of the cure period.

The notice has no immediate impact on the listing of the Company’s common stock, which will continue to be listed and traded on the NYSE during this period, subject to the Company’s compliance with other listing standards, under the symbol “HK.”

Item 7.01      Regulation FD Disclosure.

On August 27, 2015, the Company issued a press release announcing that it had entered into certain exchange agreements and that it had received the notice of noncompliance with the NYSE continued listing standard.

A copy of the press release is furnished herewith as Exhibit 99.1 and incorporated herein by reference.

Item 8.01      Other Events.

On August 27, 2015, the Company entered into separate, privately negotiated exchange agreements with certain holders (the “Holders”) of the Company’s 9.75% senior notes due 2020 (the “2020 Notes”), 8.875% senior notes due 2021 (the “2021 Notes”) and 9.25% senior notes due 2022 (the “2022 Notes” and together with the 2020 Notes and 2021 Notes, the “Senior Unsecured Notes”), pursuant to which the Company has agreed to issue approximately $1.02 billion aggregate principal amount of new 13.0% Third Lien Senior Secured Notes due 2022 (the “New Notes”) in exchange for approximately $1.57 billion aggregate principal amount of Senior Unsecured Notes held by such Holders, consisting of $497.2 million principal amount of 2020 Notes, $774.7 million principal amount of 2021 Notes and $294.3 million principal amount of 2022 Notes. Holders will also receive a cash payment from the Company in amounts equal to the accrued and unpaid interest on the Senior Unsecured Notes that are exchanged for New Notes.

The New Notes will be secured by third-priority liens on substantially all of the Company’s and its subsidiary guarantors’ assets that secure the Company’s senior secured revolving credit facility. The indenture governing the New Notes will include covenants substantially similar to those governing the Company’s outstanding 8.625% senior secured notes.

The Company expects to close the debt exchanges within 10 business days, subject to customary closing conditions, including an amendment to its senior secured revolving credit facility to, among other things, permit the issuance of the New Notes.

The Company offered the New Notes to the holders of Senior Unsecured Notes in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended. The Company relied on this exemption from registration based in part on representations made by the Holders of Senior Unsecured Notes.
