Gibraltar Announces 30% Increase in Third Quarter Revenue

Sales Volume Leverage and Streamlined Cost Structure Drive Eightfold Increase in EPS

Buffalo, New York, November 2, 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 nine months ended September 30, 2011.

Management Comments

“Gibraltar achieved another quarter of excellent top- and bottom-line results,” said Gibraltar Chairman and Chief Executive Officer Brian Lipke. “We grew sales 30%, including double-digit organic growth as well as a 17% increase from acquisitions. Our adjusted gross margin improved by 330 basis points, and we delivered 550% growth in adjusted income from continuing operations.”

“Gibraltar’s impressive performance reflects the success of our three-point growth strategy,” said Lipke. “This strategy includes focusing on operational excellence across the company, increasing our market share, and capitalizing on the strength of our balance sheet to make accretive acquisitions. As a result, we have been able to report consistently solid financial results in a challenging end-market environment.”

“Our long-term goal is to position Gibraltar as the low-cost global supplier,” said Gibraltar President and Chief Operating Officer Henning Kornbrekke. “We have made great strides toward that goal during the past few years through lean initiatives that have lowered our cost structure. At the same time, we have significantly reduced working capital and more effectively managed commodity costs. Our third-quarter financial performance is the result of these efforts, and we continued to make progress in each of these areas during the quarter.”

“In addition, we are aggressively executing on our organic growth strategy, which centers on launching new products, expanding our geographic market coverage, and leveraging our competitive strengths to penetrate new end markets adjacent to our core business,” said Kornbrekke. “As a result, we are continuing to shift Gibraltar’s overall business mix away from the residential building market and toward industrial construction and infrastructure, and our recent acquisitions have accelerated our progress in that direction.”

Financial Results

Net sales for the third quarter of 2011 increased 30% to $220.1 million from $169.7 million for the third quarter of 2010, including $28.9 million in revenues from two second-quarter 2011 acquisitions. GAAP income from continuing operations was $7.4 million, or $0.24 per diluted share, compared with $0.8 million, or $0.03 per diluted share for the third quarter last year. Results from the third quarter of 2011 and 2010 included after-tax special charges of $0.4 million for each period, resulting from acquisition-related costs and exit activity costs related to business restructuring. Adjusting for these items, Gibraltar’s third-quarter 2011 adjusted income from continuing operations increased 550% to $7.8 million, or $0.26 per diluted share, from $1.2 million, or $0.04 per diluted share, in the third quarter of 2010.

Adjusted gross margin increased to 19.8% in the third quarter of 2011 from 16.5% in the third 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 acquisitions. Adjusted selling, general and administrative expense increased 5% to $24.5 million for the third quarter of 2011 from $23.3 million a year earlier, primarily reflecting the net result of the addition of the acquisitions in the second quarter which were nearly offset by lower compensation costs. Adjusted selling, general, and administrative expenses were 11.1% of net sales, 260 basis points lower than the third quarter of 2010.

For the nine months ended September 30, total net sales increased 20% in 2011 to $592.5 million from $493.3 million in 2010. Gibraltar’s GAAP income from continuing operations for the first nine months of 2011 was $16.1 million, or $0.52 per diluted share, compared with $1.0 million, or $0.03 per diluted share, in 2010. Results for the first nine months of 2011 included after-tax special charges of $4.3 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 nine months of 2010 included $1.5 million largely resulting from an ineffective interest rate swap and restructuring charges. Adjusting for these items, Gibraltar’s first nine months of 2011 adjusted income from continuing operations was $20.4 million, or $0.67 per diluted share, compared with adjusted income from continuing operations of $2.5 million, or $0.08 per diluted share, in 2010.

Liquidity and Capital Resources

•

Gibraltar’s liquidity was $158 million as of September 30, 2011, including cash on hand of $33 million and availability under the revolving credit facility.

•

The Company invested $12.1 million in working capital since December 31, 2010, as 20% sales growth in the first nine 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 63 for the third quarter of 2011, sustaining the Company’s improvement in managing working capital.

•

The Company used cash and debt available under its revolving credit facility to help finance the D.S. Brown and Pacific Award Metals acquisitions in the second quarter. The strong cash flow of the third quarter enabled the Company to fully repay all amounts drawn on the revolving credit facility in September.

•

Subsequent to quarter end, the Company amended its Senior Credit Agreement to extend the due date of the $200 million revolving credit facility for five years as well as secure a $35 million term loan commitment, reduce Gibraltar’s cost of borrowing, and provide additional financial flexibility.

Outlook

“We are enthusiastic about our growth prospects going forward,” said Lipke. “We plan to maintain our focus on operational excellence and product leadership, while at the same time, strengthening our balance sheet and considering accretive acquisitions. We have been able to deliver solid financial results without a significant recovery in our end markets. If our end markets do begin improving, we have an excellent opportunity to leverage margin growth both from incremental sales and from portfolio management as we acquire new businesses that take us further up the value chain. Looking forward near term, we are confident that Gibraltar will continue to report significantly improved year-over-year financial results, keeping in mind the lower historical seasonal demand in the first and fourth quarters of each year.”

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 adjustments are shown in the Non-GAAP reconciliation of adjusted operating 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 and twelve months ending December 31, 2011, on February 23, 2012, and hold its earnings conference call on February 24, 2012, starting at 9:00 a.m. ET.
