Great Western Petroleum, LLC Announces Closing of Equity Recapitalization Plan and Senior Secured Second Lien Notes Offering

February 2021 – Denver, CO

Great Western Petroleum, LLC (the “Company”) today announced that it has completed its previously announced comprehensive equity recapitalization transaction (the “Recapitalization Transaction”). The Company has amended and restated its limited liability company agreement to effect the exchange of all outstanding preferred units for new common units. This exchange results in the elimination of annual preferred distributions of approximately $23.7 million. In addition, as part of the Recapitalization Transaction, The Broe Group has made an additional equity investment in the Company.

Concurrently with the Recapitalization Transaction, the Company and its wholly owned subsidiary, Great Western Finance Corp., as co-issuer (“Finance Corp.” and, together with the Company, the “Issuers”), completed their previously announced offering (the “Offering”) of $235 million aggregate principal amount of 12.000% Senior Secured Second Lien Notes due 2025 (the “Notes”). The Notes will mature on September 1, 2025. The completion of the Offering was a condition precedent to the consummation of the Recapitalization Transaction. The net proceeds from the Offering will be used to redeem in full the Issuers’ outstanding 9.000% Senior Notes due 2021 (the “2021 Notes”), which redemption is expected to occur on March 3, 2021. The net proceeds from the Offering were irrevocably deposited with the trustee under the 2021 Notes, along with cash on hand, to satisfy and discharge all of the Issuers’ remaining obligations under the indenture governing the 2021 Notes. Upon such satisfaction and discharge, the indenture governing the 2021 Notes is generally no longer in effect.

Additionally, in connection with the completion of the Offering and the Recapitalization Transaction, the Issuers have exchanged all $75 million aggregate principal of their outstanding 8.500% Senior Notes due 2025 (the “Prior 2025 Notes”) for additional Notes (the “Private Exchange”). The Issuers paid accrued and unpaid interest on the Prior 2025 Notes with cash on hand through, but not including, the date of the Private Exchange. The Notes issued in the Private Exchange constitute “Additional Notes” under the indenture governing the Notes and will comprise one series with the Notes issued in the Offering. As a result of the Private Exchange, there are no Prior 2025 Notes outstanding and the indenture governing the Prior 2025 Notes is no longer in effect.

The Notes have not been, and will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and the rules promulgated thereunder and applicable state securities laws. The Notes were offered only to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act and non-U.S. persons in transactions outside the United States in reliance on Regulation S under the Securities Act.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy any security, nor shall there be any sale of the Notes or any other security of the Issuers, in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. This press release does not constitute a notice of redemption under the optional redemption provisions of the indenture governing the 2021 Notes.
