NYSE TO COMMENCE DELISTING PROCEEDINGS WITH RESPECT TO HYPERDYNAMICS CORPORATION
February 23, 2015

NEW YORK, February 23, 2015 – The New York Stock Exchange (“NYSE” or the “Exchange”) announced today that the staff of NYSE Regulation, Inc. had determined to commence delisting proceedings with respect to the common stock of Hyperdynamics Corporation (the "Company") – ticker symbol HDY.

NYSE Regulation reached this delisting determination based upon a review of the Company’s performance under its previously approved business plan to address its non-compliance with the NYSE’s continued listing standards. The Company had fallen below the standard in Section 802.01B of the NYSE Listed Company Manual as its average global market capitalization over a consecutive 30 trading day period was less than $50,000,000 and its stockholders’ equity was less than $50,000,000.

The Company has a right to a review of this determination by a Committee of the Board of Directors of NYSE Regulation (the “Committee”). If the Company requests a review by the Committee, the NYSE will announce the date of such review. The NYSE will announce the date on which it will suspend trading, if applicable, in the Company’s common stock at such time as its appeal rights expire or sooner, if there is a material adverse development. The NYSE would then apply to the Securities and Exchange Commission to delist the common stock.
