NCI BUILDING SYSTEMS ACHIEVES EARNINGS GUIDANCE FOR

FIRST-QUARTER FISCAL 2007

AFFIRMS FISCAL 2007 EARNINGS GUIDANCE IN RANGE OF $4.55 TO $4.80

ANNOUNCES BOARD AUTHORIZATION OF

NEW STOCK REPURCHASE PLAN OF UP TO 1 MILLION SHARES

HOUSTON (February 28, 2007) – NCI Building Systems, Inc. (NYSE: NCS) today announced financial results for the first quarter ended January 28, 2007. Sales increased 23% for the quarter to $359.3 million from $293.3 million for the first quarter of fiscal 2006. Net income for the first quarter of fiscal 2007 was $10.5 million, or $0.49 per diluted share, which included a $0.03 dilutive impact from NCI’s 2.125% Convertible Senior Subordinated Notes (the “Notes”). Excluding the impact of the Notes, adjusted net income per diluted share was $0.52, within the Company’s range of guidance for the quarter. Net income for the first quarter of fiscal 2006 was $12.9 million, or $0.62 per diluted share, which included a $0.02 dilutive impact from the Notes.

Norm Chambers, President and Chief Executive Officer of NCI, commented, “We were pleased to achieve our earnings guidance for the first quarter, a period about which we were correct to be cautious. Our Engineered Building Systems segment drove our results for the quarter, with sales growth of more than 80% and a more than doubling of operating income. This growth supported increased intersegment sales with both the Metal Components and Metal Coil Coating segments, which was more than offset by the impact of lower third-party sales at both of these businesses.

“While the business outlook for fiscal 2007 remains attractive, we now expect the combination of excess industry inventory and winter weather will affect our second quarter as it did the first, producing similar operating results. Consistent with our long-term focus on cost control and the value of a strong financial position, we have initiated an overhead expense reduction program targeting $15 million to $20 million for fiscal 2007. We are also reducing our capital expenditure plan for fiscal 2007 to approximately $50 million from our original budget of approximately $60 million. This latter decision reflects our determination to achieve our debt reduction goals, while maintaining stock repurchase flexibility and our commitment to the major manufacturing and engineering automation projects primarily being funded by our fiscal 2007 capital expenditures.

“For the first quarter of fiscal 2007, Buildings sales increased 83% to $218.0 million, including an 89% increase in third party sales. While majority of this growth in this seasonally slow quarter was related to the acquisition of Robertson-Ceco Corporation (RCC) in April 2006, the operating leverage generated by this growth, combined with increased efficiencies captured through our integration initiatives, produced an increase in operating margin for third-party Buildings sales to 10% from 9% for the first quarter of fiscal 2006. We completed the first quarter with a backlog of $365 million, nearly double the backlog of $185 million at the end of the comparable prior-year quarter.

“Components sales were $157.0 million for the latest quarter, down from $174.8 million for the comparable quarter in fiscal 2006. As expected, the Components market had an oversupply of inventory during the quarter, and we responded with commercial discipline, which we continue to believe is in our best long-term interests as the market leader, in spite of the short-term impact. The Components operating margin on third-party sales, at 9% for the quarter compared with 14% for the first quarter of fiscal 2006, reflected the deleveraging effect of this sales reduction.

“Sales for the Coatings segment were $59.2 million for the first quarter of fiscal 2007 versus $63.3 million for the first quarter of fiscal 2006, even though intersegment volume primarily related to RCC rose 25% for the quarter. As anticipated, third-party sales included a greater level of tolling, again related to heavy industry inventory levels. Due primarily to the base-loading impact of greater intersegment sales, the Coatings operating margin on third party sales increased to 28% for the latest quarter from 15% for the first quarter of fiscal 2006.

“In addition to the normal seasonal sales impact, which has been magnified by severe winter weather, we expect the second quarter of fiscal 2007 will continue to be affected by excess inventory, which will challenge our ability to expand sales in Components and Coatings. As a result, we have established our guidance for earnings per diluted share for the second quarter in a range of $0.50 to $0.55. Our guidance excludes any potential share dilution related to NCI’s Notes, because that amount, if any, will be dependent upon the future price of the Company’s stock

“In spite of our outlook for the first half of fiscal 2007, our quoting activity has been consistent with industry expectations for continued growth during the seasonally busy part of the year, which coincides with the second half of our fiscal year. Among these industry expectations, the Dodge Report’s projected 2007 growth in industry square footage remains at 2% and dollar value at 6%. Based on our outlook for industry activity and our solid backlog, we continue to expect to produce 10% growth in tons shipped for the fiscal year and increase average plant utilization to approximately 80%. We also continue to expect our income tax rate for fiscal 2007 to be approximately 39%. Due to recent indications from steel producers, we now expect the average weighted cost of steel to increase as the fiscal year progresses.

“Based on these assumptions, we affirm our guidance for fiscal 2007 earnings per diluted share in a range of $4.55 to $4.80. Our guidance excludes any potential share dilution related to NCI’s Notes, because that amount, if any, will be dependent upon the future price of the Company’s stock.”

Mr. Chambers concluded, “As our guidance indicates, we expect the second half of fiscal 2007 to drive the fiscal year’s results consistent with historical patterns. In spite of expectations that the seasonally weak first half of the fiscal year will be somewhat below our original budgets, our substantial backlog, our cost reduction and capital expenditure initiatives and the completion of the Garco Building Systems acquisition all support our confidence in our ability to meet our guidance. The Company has made this confidence tangible through the Board’s authorization of a new 1 million share stock repurchase plan.”
