Gibraltar Announces Second Quarter Results

Sales Grow 18%; Drives EPS Up 166%

Buffalo, New York, August 3, 2011 – Gibraltar Industries, Inc. (Nasdaq: ROCK), a leading manufacturer and distributor of products for building and industrial markets, today reported its financial results for the three and six months ended June 30, 2011.

Net sales for the second quarter of 2011 increased $32 million or 18% to $208.8 million, from $176.9 million for the second quarter of 2010, including $22 million in revenues from two second quarter acquisitions. GAAP income from continuing operations was $7.2 million, or $0.24 per diluted share, an increase of 166% from $0.09 per diluted share for the second quarter last year. Results from the second quarter of 2011 included after-tax special charges of $2.1 million, resulting from acquisition-related costs and exit activity costs related to business restructuring. Results from the second quarter of 2010 include $0.3 million of after-tax restructuring charges. Adjusting for these items, Gibraltar’s second-quarter 2011 adjusted income from continuing operations increased 233% to $9.3 million, or $0.30 per diluted share, from $2.9 million, or $0.09 per share, in the second quarter of 2010.

Adjusted gross margin increased to 23% in the second quarter of 2011 from 19% in the second quarter of 2010. The increase was primarily due to a more favorable alignment of raw material costs and customer selling prices, cost reductions, and the impact of the recent higher margin acquisitions. Adjusted selling, general and administrative expense increased 11% to $27.3 million for the second quarter of 2011 from $24.5 million a year earlier, primarily reflecting the Company’s acquisitions this quarter. Adjusted selling, general, and administrative expenses were 13.1% of sales, 70 basis points lower than the second quarter of 2010.

Management Comments

“Gibraltar performed well in the second quarter, especially in light of the limited improvements in our major end markets,” said Gibraltar Chairman and Chief Executive Officer Brian Lipke. “We entered the year confident, given our progress in cost cutting and strategically repositioning the business, the Company could attain profitability in a lackluster demand environment. In line with these expectations, this was the second quarter in a row that we have been able to generate significant year-over-year improvements in sales and profitability, and we expect to generate favorable year-over-year comparisons in the second half of the year.”

“Capitalizing on our broad, competitive product lines, our nationwide manufacturing and distribution footprint, and our available manufacturing capacity, we have been focused on capturing additional share in the residential market, focused primarily on the repair and remodel segment,” Lipke said. “We also are continuing to expand Gibraltar’s position in the industrial sector, as well as in the nonresidential building market. Our efforts in these areas have been successful, as evidenced by the good organic growth we achieved this quarter despite continued weak conditions in the housing market.”

“At the same time, leveraging the strength of our balance sheet and our favorable liquidity position, we were successful in finding new avenues for expanding the business in addition to organic growth,” said Gibraltar President and Chief Operating Officer Henning Kornbrekke. “Our two recent acquisitions not only contributed to our double-digit top-line growth, but also improved Gibraltar’s profitability and operating performance characteristics.”

“In addition to these acquisitions, earlier this year we took another step in our long-term effort to strategically reposition the Company by divesting our structural connectors business,” Kornbrekke said. “This has allowed us to focus our attention strictly on higher-margin building product opportunities, and invest in operating systems which, among other things, have enabled us to more effectively manage the volatility in raw material prices. With these initiatives, along with our lower cost structure, we have successfully positioned Gibraltar to be profitable even at today’s subdued levels of end-market activity.”

For the six months ended June 30, total net sales increased 15% in 2011 to $372.4 million from $323.6 million in 2010. The Company’s GAAP income from continuing operations for the first half of 2011 was $8.7 million, or $0.28 per diluted share, compared with $0.2 million, or $0.01 per diluted share, in 2010. Results from the first half of 2011 included after-tax special charges of $3.9 million for acquisition-related costs, exit activity costs related to business restructuring, and equity compensation declined by Mr. Lipke. After-tax special charges for the first half of 2010 included $1.1 million largely for an ineffective interest rate swap.

Adjusting for these items, Gibraltar’s first half 2011 adjusted income from continuing operations was $12.6 million, or $0.41 per share, compared with adjusted income from continuing operations of $1.3 million, or $0.04 per share, in 2010.

Liquidity and Capital Resources

• Gibraltar’s liquidity was $129 million as of June 30, 2011, including cash on hand of $21 million.

• The Company invested $29 million in working capital since December 31, 2010, as 15% sales growth in the first six months of 2011 increased the investment in accounts receivable and inventories. Days of net working capital, which consists of accounts receivable, inventory and accounts payable, were 61 for the second quarter of 2011, sustaining the Company’s improvement in managing working capital.

• The Company used cash and debt available under its revolver to finance the D.S. Brown and Pacific Award Metals acquisitions this quarter. As of June 30, 2011, the Company had $20 million outstanding under the revolver.

Outlook

“Gibraltar has encouraging prospects for organic growth,” said Lipke. “However, seasonal cyclicality in the second half of the year can be challenging, and we expect moderating demand levels in the second half of 2011, including new housing starts which are likely to remain a headwind at least through the end of the year, if not longer. However, we have been successful in shifting our business mix toward the industrial and, more recently, the infrastructure markets, where there is clearly greater propensity to spend on deferred repair and maintenance and invest in new production capacity as the economic outlook improves.”

“We believe that Gibraltar is well-positioned to capitalize on the pockets of opportunity that appear in our markets through both acquisitions and internally generated growth,” Lipke said. “At the same time, our reduced cost structure and improving operational efficiency provide us with significant ability to leverage future top-line growth. As a result, we believe that Gibraltar will continue to deliver improved sales and profitability in the second half of 2011 compared to the comparable periods of 2010.”

Safe Harbor Statement

Information contained in this news release, other than historical information, contains forward-looking statements and is subject to a number of risk factors, uncertainties, and assumptions. Risk factors that could affect these statements include, but are not limited to, the following: the availability of raw materials and the effects of changing raw material prices on the Company’s results of operations; energy prices and usage; changing demand for the Company’s products and services; changes in the liquidity of the capital and credit markets; risks associated with the integration of acquisitions; and changes in interest and tax rates. In addition, such forward-looking statements could also be affected by general industry and market conditions, as well as general economic and political conditions. The Company undertakes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by applicable law or regulation.

Non-GAAP Financial Data

To supplement Gibraltar’s consolidated financial statements presented on a GAAP basis, Gibraltar also presented certain adjusted financial data in this news release. Adjusted financial data excluded special charges consisting of intangible asset impairment, restructuring primarily associated with the closing and consolidation of our facilities, acquisition-related costs, surrendered equity compensation, deferred tax valuation allowances, and interest expense recognized as a result of our interest rate swap becoming ineffective. These adjusted adjustments are shown in the adjusted reconciliation of results excluding special charges provided in the financial statements that accompany this news release. We believe that the presentation of results excluding special charges provides meaningful supplemental data to investors, as well as management, that are indicative of the Company’s core operating results and facilitates comparison of operating results across reporting periods as well as comparison with other companies. Special charges are excluded since they may not be considered directly related to our ongoing business operations. These adjusted measures should not be viewed as a substitute for our GAAP results, and may be different than adjusted measures used by other companies.

Next Earnings Announcement

Gibraltar expects to release its financial results for the three months ending September 30, 2011, on November 2, 2011, and hold its earnings conference call on November 3, 2011, starting at 9:00 a.m. ET.
