MIDLAND, Texas – Permian Resources Corporation (“Permian Resources”) (NYSE: PR) announced today that Permian Resources Operating, LLC (the “Issuer”), a subsidiary of Permian Resources, has priced its previously announced private placement pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (the “Securities Act”), to eligible purchasers of $500.0 million aggregate principal amount of 7.000% senior notes due 2032 (the “Notes”). The Notes mature on January 15, 2032 and pay interest at the rate of 7.000% per year, payable on January 15 and July 15 of each year. The first interest payment on the Notes will be made on January 15, 2024. The Notes were priced at 99.50% of par, plus accrued and unpaid interest from September 12, 2023. The Notes will be guaranteed on a senior unsecured basis by Permian Resources and all of the Issuer’s subsidiaries that guarantee the Issuer’s obligations under its senior secured credit facility (the “credit facility”). The Issuer intends to use the net proceeds from this offering to repay all or a portion of the amounts outstanding under its credit facility and any remaining net proceeds for general corporate purposes. The Notes Offering is expected to close on December 13, 2023, subject to customary conditions.

The Notes are being offered as additional notes under the indenture dated as of September 12, 2023, as may be supplemented from time to time, pursuant to which the Issuer has previously issued $500.0 million aggregate principal amount of 7.000% Senior Notes due 2032 (the “Existing Notes”). The Notes will have substantially identical terms, other than the issue date and issue price, as the Existing Notes, and the Notes and the Existing Notes will be treated as a single series of securities under the Indenture and will vote together as a single class.

The Notes have not been registered under the Securities Act, or any state securities laws, and, unless so registered, the Notes 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 applicable state securities laws. The Issuer plans to offer and sell the Notes only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the United States pursuant to Regulation S under the Securities Act.

This communication shall not constitute an offer to sell, or the solicitation of an offer to buy, any of the Notes, nor shall there be any sale of the Notes in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
