Reliance Steel & Aluminum Co. (NYSE:RS) announced today that it has amended and restated its existing $1.1 billion unsecured revolving credit facility for five years and increased the size to $1.5 billion.

Hannah, Chairman and CEO of Reliance, said, "We were pleased with the response from our existing bank group and appreciate their continued support, as well as the strong interest from new banks. Our credit facility now includes 26 banks, compared to 16 banks in our prior facility. The increased size of the credit facility will allow us to continue our growth of existing operations as well as anticipated acquisition opportunities. The more favorable pricing terms in the new facility will also contribute to our earnings."

Bank of America, N.A. is the Administrative Agent and Merrill Lynch, Pierce, Fenner & Smith Incorporated, J.P.Morgan Securities LLC and Wells Fargo Securities, LLC were the Joint Lead Arrangers and Joint Book Managers.
