HOUSTON -- After assessing the impact of Hurricane Katrina on its onshore and offshore operations in the Gulf Coast region, Petrohawk Energy Corporation ("Petrohawk" or the "Company") (Nasdaq:HAWK) announced today that its facilities did not experience any material damage.

As more information becomes available, Petrohawk will determine if any adjustments to production guidance are warranted.
