Reported Operating Income of $0.04 Per Diluted Share

Insulating Glass Spacer Facility Consolidation Completed in August

Engineered Products Group Outperformed Its End Market

Cash & Equivalents of $62 million

HOUSTON, Sept. 4, 2012 (GLOBE NEWSWIRE) -- Quanex Building Products Corporation (NYSE:NX), a leading manufacturer of engineered materials, components and systems serving domestic and international window and door OEMs through its Engineered Products and Aluminum Sheet Products Groups, today released fiscal 2012 third quarter results for the period ending July 31, 2012.

Third quarter 2012 consolidated net sales were $237.9 million, compared to $252.4 million a year ago. Third quarter 2012 diluted income from continuing operations was $0.04 per share compared to diluted income of $0.24 share a year ago. The table below details certain income/expense items recognized in the third quarter of 2012 and 2011.

Engineered Products Group (EPG) is focused on providing window and door OEMs with fenestration components, products, and systems. Key end markets are residential repair & remodel (R&R) and new home construction.

EPG's third quarter 2012 net sales were $134.1 million compared to $124.1 million a year ago. The 8% improvement in sales was predominantly related to higher vinyl extrusion sales.

EPG's third quarter 2012 operating income was $13.1 million compared to $14.1 million a year ago, and included an Insulating Glass (IG) warranty benefit from a change in estimate of $0.8 million.  Expenses related to the IG facility consolidation were $2.5 million in the quarter. There was no related consolidation expense in the year ago quarter. 

EPG "same store" sales for the 12 months ended July, 2012 were up 6% from the previous 12 months, compared to total U.S. window shipments as reported by Ducker Worldwide down 2% over the same period.  EPG is expected to report operating income of about $30 million in the second half of 2012, excluding $3 million of IG spacer consolidation expenses.

IG Spacer Consolidation Program

On November 7, 2011, Quanex announced a consolidation program for its IG spacer manufacturing facility in Barbourville, KY into its IG spacer manufacturing facility in Cambridge, OH. The cash costs associated with the program, completed in August 2012, were approximately $13 million through quarter end, and about $8 million of these costs were expensed. The Barbourville facility is now closed and is being prepared for sale. Quanex expects a payback period on its investment of about 2.6 years, based on annual, pre-tax cash savings of $9 million, which is expected to begin in fiscal 2013.

Aluminum Sheet Products Group is a leading provider of aluminum sheet through its Nichols Aluminum operation. Key end markets are residential repair & remodel (R&R) and new home construction.

Nichols Aluminum's third quarter 2012 shipments, net sales, operating loss, and spread (sales less material costs) were 75 million pounds, $107.0 million, $3.2 million and $0.38 per pound, respectively. Shipments were modestly down from the year ago quarter due primarily to a temporary equipment-related outage at the group's casting facility. The spread was down 22% from the year ago quarter due to a larger reduction in aluminum prices than the reduction in material costs. Customer demand remained strong through the quarter, and that demand is expected to carry through the fourth quarter.

Compared to the year ago quarter, the operating loss reflected: reduced shipped pounds; $2.1 million of strike-related semi-finished coil purchase expenses; and the impact of a lower spread.

Nichols Aluminum's shipments for the 12 months ended July 31, 2012, were down 18% from the previous 12 months, versus industry shipments as reported by the Aluminum Association that were up 6% over the same period. This underperformance is primarily attributed to the impact of a strike in the second quarter, facility performance issues, and weaker residential demand, where it has a larger presence, compared to relatively stronger distribution and transportation demand, where it has a smaller presence.

For the second half of 2012, Nichols is expected to ship roughly 150 million pounds (up modestly from the second half of 2011) at an estimated spread of $0.40 per pound (down $0.10 from second half of 2011), and generate operating income of about $3 million, excluding the $2.1 million of strike-related, carryover expenses associated with Nichols' purchase of semi-finished coils.

As previously reported, the Nichols Aluminum Decatur facility has experienced recurring quality issues with its painted aluminum sheet. In an effort to significantly improve the quality and efficiency of the facility, the company anticipates replacing the paint line's drying oven. The project is estimated to cost $6 million and is targeted to be completed during the December 2012 shutdown.

Corporate and Other Items

Corporate expenses in the quarter were $8.4 million, including ERP expenses of $1.9 million.

Third Quarter 2012 Balances

At quarter end, Quanex had a cash balance of $62.3 million and total debt outstanding of $1.3 million. Cash provided by operating activities for the 9 months ended was $6 million. The company had no borrowings under its $270 million revolving credit facility at quarter end, however, due to the facility's EBITDA covenant requirements, the available capacity was approximately $141 million at the end of the quarter. Future uses of cash could be to fund organic growth activities, fund cash dividends on the company's common stock, make acquisitions, and repurchase outstanding shares. During the third quarter, the company did not purchase any outstanding common stock.

Business Outlook

Difficult macro-economic factors will continue to create tough market conditions for Quanex. The company currently expects calendar year 2012 U.S. window shipments to be about 39 million units, essentially in-line with Ducker's 2012 forecasted shipments of 39.6 million. Quanex noted that while industry shipments of finished windows for the residential new home construction market continued to show meaningful improvement over 2011, residential R&R window shipments, a key end market for its Engineered Products Group, remained flat to last year. The company remains positive on the long term prospects of its end markets and continues to invest in its future.

Dividend Declared

As previously announced on August 30, 2012, the Board of Directors declared a quarterly cash dividend of $0.04 per share on the company's common stock, payable September 28, 2012, to shareholders of record on September 14, 2012.
