Exhibit 99.1

Hyperdynamics Receives Notification from NYSE of

Non-compliance with a Continued Listing Standard

HOUSTON, May 18, 2012 — Hyperdynamics Corporation (NYSE: HDY) announced today that, on May 14, 2012, the New York Stock Exchange (NYSE) provided notice to Hyperdynamics that it did not satisfy one of the NYSE’s standards for continued listing applicable to Hyperdynamics’ common stock.  The NYSE noted specifically that Hyperdynamics was “below criteria” for the NYSE’s price criteria for common stock because the average closing price per share of Hyperdynamics’ common stock was less than $1.00 per share over a consecutive 30-trading-day period.

Under the NYSE’s rules, in order to cure the deficiency for this continued listing standard, both Hyperdynamics’ share price and the average share price (over a consecutive 30-trading-day period), must exceed $1.00 by six months following receipt of the non-compliance notice.  Its shares will continue to be listed and traded on the NYSE during this period, subject to the Company’s continued compliance with the NYSE’s other listing requirements.

As required by the NYSE rules, Hyperdynamics will notify the NYSE, within 10 business days of receipt of the non-compliance notice, of its intent to cure the price deficiency and return to compliance with this continued listing standard.
