Antero Resources Announces Borrowing Base Increase to $1.55 Billion

DENVER, May 7, 2012  /PRNewswire/ -- Antero Resources announced today that the borrowing base under its bank credit facility has been increased to $1.55 billion.  This represents a $350 million increase over Antero's previous borrowing base which was determined in October 2011.  Lender commitments under the facility were increased to $950 million, a $100 million increase.  The $950 million commitment can be expanded to the full $1.55 billion borrowing base upon bank approval.  Antero also entered into an amendment with its bank group to increase the $1.5 billion maximum amount of the revolving credit facility to $2.5 billion in order to allow for future borrowing base growth.        

All banks participating in Antero's bank syndicate, which was formed in 2010, continue to be lenders in the credit facility, along with three new institutions.  The bank syndicate, which is co-led by J.P. Morgan Securities, LLC and Wells Fargo Securities, LLC, is a diversified group consisting of nine domestic and seven foreign institutions.  Antero currently has $215 million drawn under the credit facility and $21 million in letters of credit outstanding, resulting in approximately $715 million of readily available liquidity and approximately $1.3 billion of unused borrowing base capacity.  The next regular borrowing base redetermination is expected to occur in October 2012.  Antero has only $25 million of debt maturing before 2016.

Antero Resources is an independent oil and natural gas company engaged in the acquisition, development and production of unconventional natural gas properties primarily located in the Appalachian Basin in West Virginia and Pennsylvania, the Piceance Basin in Colorado and the Arkoma Basin in Oklahoma.  Our website is www.anteroresources.com.
