Quanex Building Products Corporation Fiscal 2009 Fourth Quarter and Annual Results

         Better Than Expected Seasonal Demand in the Quarter
     Fourth Quarter $0.41 Diluted EPS from Continuing Operations
                  $124 Million Cash and Equivalents
       Company Outperformed its Market for the Quarter and Year

HOUSTON, Dec. 3, 2009 (GLOBE NEWSWIRE) -- Quanex Building Products Corporation (NYSE:NX) today reported fiscal fourth quarter 2009 and full-year fiscal 2009 results for the period ending October 31. With fourth quarter net sales of $194.9 million, Quanex reported income from continuing operations of $15.3 million, which included $0.7 million of after-tax LIFO income primarily associated with its Aluminum Sheet Products segment. Earnings from continuing operations were $0.41 per diluted share in the quarter, which included $0.02 per diluted share of LIFO income. The company reported seasonal demand was better than expected at its two operating segments -- Engineered Products and Aluminum Sheet Products. Also, fourth quarter results benefitted from a better than anticipated aluminum spread (sales less material costs).

For the fiscal year, the company's net sales were $585.0 million. The loss from continuing operations was $137.1 million, which included an after-tax impairment charge of $141.4 million and after-tax LIFO income of $4.8 million. Loss from continuing operations was $3.67 per diluted share, which included $3.79 per diluted share of impairment charges and $0.13 per diluted share of LIFO income. Excluding impairment charges and LIFO income, the company had a fiscal 2009 loss of $0.01 per diluted share from continuing operations.

Engineered Products is focused on providing leading OEM window and door customers with value-added fenestration components, products, and systems. Key market drivers are U.S. residential housing starts and remodeling activity.

"The U.S. residential new housing market dropped 30% in our fourth quarter compared to a year ago, while residential remodeling activity was estimated to be off about 10%," said David D. Petratis, president and chief executive officer of Quanex Building Products. "The Engineered Products segment outperformed the overall market with fourth quarter sales down 12% from the year ago period. Our sales performance was better than expected as the seasonal pick-up we experienced in residential building and remodeling activity in the third quarter carried through our fourth quarter, with October sales particularly noteworthy. We also saw our OEM customers capture additional residential remodeling and repair business. The segment's operating income was a healthy $15.2 million, 50% higher than the year ago quarter, the result of stronger shipments, better mix and higher average selling prices."

"We are pleased with the relatively strong performance of Engineered Products, particularly in the second half of the year, and although difficult to quantify, we do believe the segment benefited from the $1,500 energy tax credit window program and the $8,000 first time homebuyer's tax credit that was recently extended through June 2010. However, our view of the overall housing market remains guarded, and we expect the first half of fiscal 2010 to be challenging. We will continue to conservatively size our business and inventories, consistent with how we operated in 2009."

     charge of $20.4 million.

Aluminum Sheet Products is a leading provider of common alloy aluminum sheet products for the building & construction, transportation and other consumer durable markets. Key market drivers are U.S. residential housing starts and remodeling activity.

"Average aluminum prices were up in the fourth quarter compared to our sequential third quarter, which generally benefits our aluminum spread (sales less material costs). Spread was up 10% over the third quarter, better than we anticipated, but down 16% from the fourth quarter last year," Petratis said. "Shipments in the quarter were very healthy at 78 million pounds, off just 3% from the year ago quarter, while shipments in the aluminum market where we compete were down 23% over the same period. Compared to the sequential third quarter, our fourth quarter shipped pounds were up an impressive 21%. Our strong shipments were attributable to a further uptick in seasonal demand, and ongoing short lead-time sales opportunities."

Cash Position

"At fiscal year end, we had a cash balance of $124 million and the company remained essentially debt-free," Petratis said. "Generating healthy cash flows was a top priority for us throughout 2009, and will remain so for 2010. Cash from operations for the year was a very respectable $60.5 million given the historically depressed year. Our uses for cash will be to continue to fund organic growth opportunities, make strategic acquisitions, and when appropriate, raise our common stock dividend and repurchase outstanding shares."

Fiscal 2010 Business Outlook

"High unemployment, relatively high inventories of new and existing homes for sale, and high rates of foreclosures will continue to be a drag on our business for the next twelve months. However, we do believe both new home construction and remodeling activity bottomed during fiscal 2009, and we expect slightly better sales and improved earnings in 2010 compared to 2009. We expect the first half of 2010 to be challenging and it is uncertain as to how long our end markets will remain at depressed levels, so we must continue to operate our businesses with reduced staffs and minimal levels of materials," said Petratis. "This uncertainty carries through to our ability to precisely estimate segment operating income for fiscal 2010."

"At this time, we expect Engineered Products to earn $25 million to $30 million in operating income in 2010, predominantly in the second half. Improved earnings in 2010 compared to 2009 will come from a combination of new product opportunities, new customers, and modest improvements in our two end markets."

"We expect Aluminum Sheet Products to earn about $10 million in operating income in 2010, predominantly in the second half. Our 2010 guidance assumes an aluminum spread generally in-line with 2009, and slightly higher shipments. This guidance represents an improvement over 2009 results that were negatively impacted by about $13 million in the first half due to high scrap inventories combined with a dramatic fall in aluminum prices. While it is problematic to predict aluminum prices, we do not expect aluminum prices to fall 60% again in 2010, nor do we expect to be impacted by high scrap inventories to the extent we were in 2009.

"Financial guidance for Engineered Products and Aluminum Sheet Products exclude estimated corporate expenses of $23 million and any impact from LIFO. Additionally, fiscal 2010 estimates for capital expenditures, and depreciation & amortization are $22 million and $30 million, respectively," concluded Petratis.

Non-GAAP Financial Measures

Income from Continuing Operations Excluding LIFO

Income from continuing operations excluding LIFO, impairments and separation related costs are non-GAAP financial measures. The Company believes these non-GAAP financial measures provide a consistent basis for comparison between quarters and enhances the understanding of the performance of its operations.

Set forth below is a reconciliation of reported income from continuing operations and reported diluted earnings per share from continuing operations to income from continuing operations excluding LIFO, impairments and separation related costs and diluted earnings per share from continuing operations excluding LIFO, impairments and separation related costs. The Company does not intend for this information to be considered in isolation or as a substitute for other measures prepared in accordance with GAAP.
