Gibraltar Announces Acquisition of Pacific Award Metals

Strengthens Gibraltar’s Position in Key Western U.S. Markets

Buffalo, New York, June 6, 2011 — Gibraltar Industries, Inc. (Nasdaq: ROCK), a leading manufacturer and distributor of building products, today announced that it has acquired privately held Pacific Award Metals Inc. in a transaction that expands Gibraltar’s product portfolio and adds new customers from its distribution network in the western United States. Terms of the agreement were not disclosed.

Headquartered in California, Pacific Award Metals is a leading west coast manufacturer of roof ventilation, roof trims, flashing and rain ware, drywall trims, and specialized clips and connectors for concrete forms used in the new construction and repair and remodel segments. Established in 1962, it manufactures and distributes from several facilities located in the western U.S. and had sales for the most recent twelve months of approximately $30 million.

“Augmenting our portfolio with some of the strongest brands in the western U.S. will establish us as the clear leader in the region’s largest building products markets,” said Gibraltar Chairman and Chief Executive Officer Brian Lipke. “Pacific Award Metals’ product portfolio and wholesale distributor relationships complement and expand those of Gibraltar. In addition, the acquisition creates opportunities to provide a broader range of products through our retail channels across the country. The Pacific Award Metals employee team has a well-earned reputation for delivering high quality products and superior customer service and we look forward to their joining Gibraltar.”

“The integration of Pacific Award Metals with Gibraltar also is expected to provide many opportunities for cost synergies.” added Gibraltar President and Chief Operating Officer Henning Kornbrekke. “As we integrate our operations, we expect to realize significant value from improved utilization of facilities plus other operating efficiencies. We expect the acquisition to be nominally accretive to earnings for the remainder of 2011, excluding acquisition and other one time costs, and to be accretive on a GAAP basis thereafter.”
