Gibraltar Industries Announces New Five-Year $235 Million Credit Facility

Buffalo, NY October 13, 2011

Gibraltar Industries, Inc. (Nasdaq: ROCK) announced today that it has closed on a new $235 million credit agreement which includes a $200 million senior secured revolving credit facility with a five-year maturity as well as a $35 million term loan commitment. The new facility replaces a $200 million senior secured revolving credit facility that was due to expire in August 2012. There were no draws on the revolver as of September 30, 2011.

In addition to the increase in the facility size, the new agreement will reduce Gibraltar’s cost of borrowing and provide additional financial flexibility. The facility will be used for general corporate purposes, including funding future acquisitions.

Ten banks participated in the transaction with KeyBank as Lead Arranger and Administrative Agent, J.P. Morgan Chase Bank and Bank of America as Co-Syndication Agents, and M&T Bank, RBS Citizens and HSBC Bank serving as Co-Documentation Agents.

“We have successfully increased the size, reduced the cost and extended the term of our credit agreement,” said Kenneth Smith, Gibraltar’s Chief Financial Officer. “We are very pleased to continue to work with a group of banks that support our growth strategy. This new agreement underscores our commitment to strengthen our balance sheet and enhance financial flexibility in order to help execute on our growth strategy. We have reduced our net debt to $207 million as of September 30, 2011, from a peak of $554 million reached in August 2007, as a result of strong cash flow aided by cost-reduction initiatives, solid operating performance, and improved working capital management.”
