“We are very encouraged by our second quarter results, as our near break-even Adjusted EBITDA was our best operating performance since the third quarter of 2007,” said Floyd Sherman, Builders FirstSource Chief Executive Officer. “We finished the current quarter with sales of $206.4 million, down just 2.4 percent compared to sales of $211.5 million in the second quarter of 2010. While U.S. single-family housing starts and average commodity prices were down 13.1 percent and 20.8 percent, respectively, over this same time period, our sales volume was up slightly, which we believe is indicative of significant market share gains during the quarter.”

Commenting on the current quarter results, Chad Crow, Builders FirstSource Senior Vice President and Chief Financial Officer, added, “Our gross margin percentage was 20.7%, up 2.4 percentage points from 18.3% in the second quarter of 2010. The primary drivers of our margin increase were improved pricing on sales of our manufactured products during the quarter, coupled with less volatility in the commodity markets. We also achieved further cost reductions for the quarter, as selling, general and administrative expenses decreased $2.5 million, or 4.8 percent, compared to the second quarter of 2010.” Continuing, he

added, “We ended the quarter with $112.0 million in liquidity, down only $3.4 million from the previous quarter. The $112.0 million in liquidity included $63.1 million in available cash and approximately $48.9 in borrowing availability under our revolving credit facility. Cash used in the current quarter was approximately $14.5 million. Of this $14.5 million, $5.3 million was due to an increase in working capital and $1.1 million related to capital expenditures. The remaining $8.1 million was used to fund interest and operating losses, and is a $6.0 million improvement over the $14.1 million of cash used to fund interest and operating losses in the second quarter of 2010.”

Mr. Sherman added, “Despite our improved results, challenges still persist in the housing industry, as the seasonally adjusted annual rate for U.S. single-family housing starts in June 2011 was 453,000, which was basically flat when compared to June 2010. However, for the current quarter actual U.S. single-family housing starts were down 13.1 percent, as compared to the second quarter of 2010. We also saw a similar level of decline in actual U.S. single-family units under construction during the quarter, as they decreased 16.7 percent from the second quarter of 2010. In the South Region, as defined by the U.S. Census Bureau, and which includes all of our markets, we saw similar trends as actual single-family housing starts were 63,700, down 13.1 percent, and single-family units under construction were 116,600, down 14.5 percent compared to the second quarter of 2010.”

Second Quarter 2011 Results Compared to Second Quarter 2010
(See accompanying financial schedules for full financial details and reconciliations of Non-GAAP financial measures to their GAAP equivalents.)

	•		Sales were $206.4 million compared to $211.5 million last year, a decrease of $5.1 million, or 2.4 percent. We estimate sales decreased 2.8 percent due to commodity price deflation, which was partially offset by a slight increase in sales volume.
	•		Gross margin percentage was 20.7 percent, up from 18.3 percent, a 2.4 percentage point increase. Specifically, margins improved 1.8 percentage points due to sales price, 0.5 percentage points due to increased sales volume combined with a decrease of fixed costs in costs of goods sold, with the remaining improvement coming from sales mix.
	•		Selling, general and administrative (“SG&A”) expenses decreased $2.5 million, or 4.8 percent. As a percentage of sales, SG&A expense decreased from 24.3 percent in the second quarter of 2010, to 23.7 percent in 2011. For the current quarter, our salaries and benefits expense, excluding stock compensation expense, was $28.0 million, a decline of $1.8 million when compared to the second quarter of 2010. Delivery expense decreased approximately $0.2 million, due to reduced vehicle and equipment lease expense which was offset somewhat by higher fuel costs.
	•		During the current quarter, we recorded $1.9 million of facility closure costs primarily related to the closure of a distribution facility in Georgia.
	•		Interest expense was $5.7 million in the current quarter, a decrease of $0.9 million from the second quarter of 2010, which was primarily due to the expiration of our interest rate swaps during the current quarter.
	•		We recorded $1.7 million of income tax expense in the second quarter of 2011, compared to a $0.3 million income tax benefit in the second quarter of 2010. We recorded an after-tax, non-cash valuation allowance of $6.8 million and $7.1 million in 2011 and 2010, respectively, related to

Builders FirstSource Reports Second Quarter 2011 Results (continued)

			our net deferred tax assets. Absent this valuation allowance, our tax benefit rate would have been 37.5 percent and 38.5 percent in 2011 and 2010, respectively.
	•		Loss from continuing operations was $15.4 million, or $0.16 loss per diluted share, compared to $18.9 million, or $0.20 loss per diluted share. Excluding facility closure costs and the valuation allowance, our loss from continuing operations per diluted share was $0.08 for the current quarter, compared to $0.12 for the second quarter of 2010, an approximate 33 percent improvement.
	•		Net loss was $15.5 million, or $0.16 loss per diluted share, compared to net loss of $19.0 million, or $0.20 loss per diluted share.
	•		Diluted weighted average shares outstanding were 94.9 million in both the second quarter of 2011 and 2010.
	•		Adjusted EBITDA was a loss of $1.3 million compared to a loss of $7.6 million last year. See reconciliation attached.

Liquidity and Capital Resources

	•		Total liquidity at June 30, 2011 was approximately $112 million, which included $63.1 million of available cash and $48.9 million in borrowing availability under our revolver.
	•		Operating cash flow was $(13.4) million for the second quarter of 2011. Operating cash flow was $(29.3) million for the second quarter of 2010, excluding the $33.8 million federal income tax refund received during the quarter.
	•		Capital expenditures in the second quarter of 2011 were $1.1 million, compared to $4.8 million in the second quarter of 2010. Capital expenditures for both years relate primarily to buyouts of expiring vehicle and equipment leases.

Outlook

Mr. Sherman concluded, “Though there continues to be a significant amount of uncertainty in the macro-economic factors that drive housing demand, we are seeing positive trends in our results in spite of the difficult environment. Due to the temporary momentum created by the expiration of the federal tax credit for first-time homebuyers during the first half of 2010, we expected comparable quarter-over-quarter results to be difficult. However, even though single-family housing starts decreased over 13 percent during the second quarter of 2011, we were able to generate a similar level of sales and higher gross margins, while also lowering our operating expenses.”

“As a result of our improved financial performance, we now expect our cash burn for fiscal year 2011 to approximate $50 million, which includes $5.3 million for the repayment of our remaining 2012 notes, and expect to end the year with total liquidity of approximately $85 million, assuming a continuation of current market conditions. This is a significant improvement over our original year-end liquidity forecast of approximately $70 million. We remain committed to prudently managing the business through these trying economic times, and are very encouraged by our recent financial results. We are appreciative of all our business partners, both customers and suppliers, and are grateful for the dedication exhibited by all Builders FirstSource employees.”
