NRG Energy Refinances its $875 Million Revolver Facility, Extends $1.8 billion of Term Loan
Commitments and Amends its Senior Secured Credit Agreement

PRINCETON, NJ; June 30, 2010—NRG Energy, Inc. (NYSE: NRG) (NRG) has concluded the refinancing of an $875 million revolver facility (new revolver), the amendment and extension of $1.8 billion of term loan commitments and synthetic letter of credit (LC) facility, and the amendment of its existing Senior Secured Credit Agreement dated June 7, 2007 (the amend & extend).

“The successful refinancing of an $875 million five-year revolver, combined with the completion of the ‘amend and extend’ to our existing term loan and synthetic letter of credit facilities, represents important milestones toward achieving strong future financial flexibility,” said Christian Schade, NRG’s Executive Vice President and Chief Financial Officer.

In anticipation of the current revolver facility’s February 2, 2011 maturity, NRG successfully concluded the syndication of its new revolver, while also extending the maturity of $1.8 billion of term loan commitments and synthetic LC commitments by two and a half years. Both the new revolver and extended portions of term loan commitments and synthetic LC commitments will mature on August 31, 2015. The non-extended portions will mature on the originally scheduled date of February 1, 2013.

Under the amend & extend, lenders have also consented to changes to certain covenants as well as reset and/or increased certain covenant baskets. These amendments also included the migration of the $1.3 billion synthetic LC facility onto NRG’s balance sheet.

For both the new revolver and extended term loans, NRG will pay an interest rate equal to LIBOR plus 3.25% while the non-extended term loan pricing will remain the same. In addition, the Company will pay a fee equal to 0.625% of the undrawn portion on the revolving credit facility. There currently are no borrowings outstanding under the revolver facility.
