Recent Developments

The Offering

On March 31, 2021, Vine Holdings priced its private placement of $950 million aggregate principal amount of its 6.750% Senior Notes due 2029 to eligible purchasers under an indenture to be dated as of the date the notes are originally issued (the “Indenture”). The notes will be Vine Holding’s senior unsecured obligations and will rank equally in right of payment to all existing and future senior indebtedness of Vine Holdings, including its obligations under the the the senior secured revolving facility under that certain Credit Agreement, dated as of March 8, 2021, by and among the Company, Citibank N.A., as the administrative agent and collateral agent, and the lenders and other entities party thereto (the “Revolving Credit Facility”) and the Company’s second lien term loan facility, dated as of December 30, 2020, by and among the Company, Morgan Stanley Senior Funding, Inc., as administrative agent and collateral agent, and the several lenders party thereto (the “Second Lien Term Loan” and together with the Revolving Credit Facility, the “Senior Credit Facilities”).

The notes will initially be fully and unconditionally guaranteed on a senior unsecured basis by each restricted subsidiary of the Company (collectively, the “Guarantors” and, each a “Guarantor”), if any, that guarantees the notes in accordance with the terms of the Indenture (excluding the current, or any future direct or indirect parent of the Company). The guarantees will rank equally in right of payment with all existing and future senior indebtedness of the Guarantors (including any such Guarantor’s guarantee of indebtedness under the Senior Credit Facilities). The notes and guarantees will be effectively subordinated to all existing and future secured indebtedness of Vine Holdings and the Guarantors, including indebtedness under the Senior Credit Facilities, to the extent of the value of the collateral securing such secured indebtedness. The notes and guarantees will be structurally subordinated to all existing and future indebtedness, claims of holders of the Company’s preferred stock and other liabilities of Vine Holding’s subsidiaries that do not guarantee the notes.

We expect the net proceeds from the Notes Offering to be approximately $937 million, after deducting the initial purchasers’ discounts and our estimated expenses. We intend to use the net proceeds from the Notes Offering to redeem all of the 8.75% Senior Notes due 2023 (the “8.75% Notes”), issued on October 18, 2017 by Vine Oil & Gas LP (“Vine Oil & Gas”) and Vine Oil & Gas Finance Corp. pursuant to that certain indenture dated as of October 18, 2017, and the 9.75% Senior Notes due 2023 (the “9.75% Notes” and, together with the 8.75% Notes, the “Existing Notes”), issued on October 3, 2018 by Vine Oil & Gas and Vine Oil & Gas Finance Corp. pursuant to that certain indenture dated as of October 3, 2018.

Neither the Offering Memorandum nor this Prospectus Supplement is an offer to purchase the Existing Notes. Further, neither the Offering Memorandum nor this Prospectus Supplement is an offer to sell the notes, and we are not soliciting offers to buy the notes, in any state where the offer or sale is not permitted. The Notes Offering is expected to close on April 7, 2021, subject to customary closing conditions.

Use of Proceeds

We used the net proceeds of our initial public offering and borrowings under our new reserve-based lending facility (the “New RBL”) to repay in full and terminate each of the Vine Oil & Gas LP’s revolving credit facility, dated as of November 25, 2014, by and among Vine Oil & Gas LP, HSBC Bank USA, National Association, as Administrative Agent, Collateral Agent, Swingline Lender and as Issuing Bank and the banks, financial institutions and other lending institutions from time to time party thereto, as amended and that certain Senior Secured Credit Agreement dated as of March 20, 2018 by and among Brix Operating LLC, the lenders from time to time party thereto, and Macquarie Investments US Inc., as administrative agent, as amended from time to time. We intend to use approximately $937 million of the net proceeds from the Notes Offering to redeem all $910 million in aggregate principal amount of our Existing Notes at a redemption price equal to 106.563% of the principal amount of the 8.75% Notes (which amount is equal to $1,065.63 per $1,000 principal amount thereof) and 107.313% of the principal amount of the 9.75% Notes (which amount is equal to $1,073.13 per $1,000 principal amount thereof), in each case plus accrued and unpaid interest, if any, up to, but excluding, the date of redemption.
