Attention Hyperdynamics Corporation Investors: Hyperdynamics Misled Investors According to a Recently Filed Class Action

SAN DIEGO and HOUSTON, March 21, 2014

Hyperdynamics Accused of Violating the Foreign Corrupt Practices Act

According to the complaint, shares of Hyperdynamics fell on multiple occasions beginning with a decline of $0.66, or nearly 15%, to close at $3.76 per share on October 1, 2013. This initial drop followed the September 30, 2013 announcement that the company had received a subpoena from the United States Department of Justice seeking documents related to the company's business practices in Guinea. Specifically, the DOJ's investigation focused on the company's efforts to obtain and retain concession rights in possible violation of the U.S. Foreign Corrupt Practices Act or U.S. anti-money laundering statutes. Shares of Hyperdynamics declined $3.07 per share, or over 58%, to close at $2.19 on March 12, 2014, after the company announced that its partner in the Guinea project, Tullow Oil Plc, ceased operations based on investigations by the DOJ and U.S. Securities and Exchange Commission regarding alleged fraud and corruption by Hyperdynamics in obtaining drilling licenses in Guinea.

The complaint further alleges that Hyperdynamics made materially false and misleading statements regarding the accuracy of the company's financial statements and its internal and financial controls. As a result, Hyperdynamics statements regarding financial performance were materially false and misleading throughout the Class Period.
