Permian Resources Corporation announced that, in connection with its post-merger integration of Earthstone Energy Inc. (Earthstone) and its subsidiaries, it has completed the liquidation of Lynden Energy Corp. (Lynden), a corporation organized under the laws of British Columbia, and as a result it has applied to the British Columbia Securities Commission (BCSC), as principal regulator, and the Ontario Securities Commission (OSC) for a joint order (the Order Sought) to cease to be a reporting issuer in British Columbia, Alberta and Ontario—the provinces of Canada in which it is a reporting issuer. Lynden was a Canadian subsidiary of Earthstone, and Permian Resources is completing the liquidation to simplify its corporate structure and reduce go forward tax obligations, as contemplated at the time of the Earthstone acquisition. This liquidation is administrative in nature and has no impact on the Company’s previously announced financial and operational results and guidance.

If the Order Sought is granted by the BCSC and the OSC, Permian Resources will cease to be a reporting issuer in any jurisdiction in Canada.

Notwithstanding a decision by the BCSC and the OSC, Permian Resources continues to be a reporting company under the Securities Exchange Act of 1934, as amended, and will continue to file periodic and current reports with the Securities and Exchange Commission (SEC), which will include financial statements and other continuous disclosure materials required to be filed by it, in accordance with the applicable securities laws of the United States and the rules of the New York Stock Exchange (NYSE) under which it continues to be listed. All such periodic and current disclosures of Permian Resources filed with the SEC are publicly available to all shareholders of Permian Resources under Permian Resources’ profile at www.sec.gov. All of Permian Resources’ shareholders who reside in Canada will continue to receive copies of any continuous disclosure materials that are required to be delivered to shareholders in the United States, in the same manner and at the same time as is required under the applicable securities laws of the United States and the rules of the NYSE.
