NCI BUILDING SYSTEMS REPORTS FIRST-QUARTER EARNINGS PER DILUTED

SHARE OF $0.39 AND ADJUSTED EARNINGS OF $0.45

HOUSTON (March 3, 2008) – NCI Building Systems, Inc. (NYSE: NCS) today announced financial results for the first quarter ended January 27, 2008. Sales for the first quarter of fiscal 2008 increased to $361.5 million compared with $359.3 million for the first quarter of fiscal 2007. Net income for the first quarter of fiscal 2008 was $7.5 million or $0.39 per diluted share compared to $0.49 per diluted share for the first quarter of fiscal 2007. NCI’s adjusted earnings per diluted share for the first quarter of fiscal 2008 were $0.45. Adjusted earnings excluded charges of $0.06 per diluted share, which consisted of an inventory charge of $0.03 related to the Coatings segment, a corporate charge of $0.02 related to executive retirement and charges of $0.01 related to exiting the Component segment’s residential overhead door product line. Adjusted earnings per diluted share for the first quarter of fiscal 2007 were $0.52, which excluded a $0.03 dilutive impact from NCI’s 2.125% Convertible Senior Subordinated Notes (the “Notes”). See page 9 for a reconciliation of all GAAP and non-GAAP financial information.

Norman C. Chambers, Chairman, President and Chief Executive Officer of NCI, remarked, “NCI produced solid operating results for the first quarter of fiscal 2008, especially given the difficult economy that began for us in early fiscal 2007. Over the latest quarter we saw a drop in new starts for nonresidential and low-rise construction, as well as increased steel prices. While we see reason for optimism on steel pricing towards the latter half of this year, we are taking a very cautious view given the unpredictability of this economy. That said, our competitive position is strong, backlog is up 12.4% from the same period last year and both working capital ratios and cash flows are strong. Further, we are confident that a good supply of competitively priced steel will remain available to us over the long-term, and our customer relationships and our product quality have never been better.”

Segment Performance

“First-quarter sales for our Buildings business were comparable with the first quarter of fiscal 2007,” continued Mr. Chambers, “and we completed the quarter with a backlog of $410 million, up 12.4% from $365 million at the same time in fiscal 2007. Consistent with trends experienced in fiscal 2007, our Buildings bookings continued to be weighted toward larger, more complex projects with longer production schedules, and the segment’s sales continued to reflect ongoing softness in the markets for small buildings. As a result, we produced third-party sales

for the first quarter that were slightly ahead of the first quarter of fiscal 2007, while lower intersegment sales related to small buildings reduced our capacity utilization and operating margin.

“Our Components business produced better than anticipated growth in tonnage for the first quarter, which increased 5% from the first quarter of fiscal 2007. This tonnage growth was driven by third-party sales, with intersegment sales declining as anticipated due to the scheduling of the Buildings backlog. Lower pricing and our decision to exit the residential overhead door product line resulted in slightly lower third-party sales and operating margin on a comparable-quarter basis.

“The results for our Coatings business for the latest quarter reflected an 18% increase in third-party sales due to a higher sales mix of package sales compared with the higher tolling sales in first quarter of fiscal 2007. These package sales masked a reduction in tonnage from third-party sales for the quarter coupled with temporarily higher material costs for intersegment sales. This reduced operating leverage coupled with a pre-tax inventory charge of approximately $0.9 million impacted the Coatings operating margin to half the level produced for the first quarter of fiscal 2007. The inventory charge resulted from adjusting the carrying values of certain painted hot-roll steel products to a manufactured standard value.”

Financial Guidance

NCI also announced today that it has revised its guidance for 2008. “Despite our strong Buildings backlog at the end of the first quarter, we believe it prudent to reduce estimated earnings per diluted share for first-half and full-year fiscal 2008,” Mr. Chambers said. “Our modification is based on significant steel price increases recently announced by certain major suppliers. We expect this will result in an increase in our weighted average cost of steel of 13% to 15% in our second quarter. Our modification is also based on the identification of the charges that impacted our first quarter, as well as additional, expected charges for the second quarter.”

Accordingly, the Company now expects earnings per diluted share for the first half in the range of $0.64 to $0.79, down from previously forecasted earnings per diluted share in the range of $0.90 to $1.05. This revised half-year guidance reflects the projected impact of the recently announced steel price increases and includes first-quarter charges of $0.06 per diluted share (discussed above) and additional charges totaling $0.05 per diluted share anticipated in the second quarter. Second-quarter charges consist of an estimated $0.03 related to exiting the residential door product line and $0.02 related to our previously disclosed executive retirement in the second quarter. The revised 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 added, “As a result, we are adjusting our original full-year fiscal 2008 guidance from $3.35 to $3.70 per diluted share to $3.09 to $3.44 per diluted share, excluding any potential share dilution related to NCI’s Notes. This adjustment gives effect to the modifications of our first-half guidance that includes the charges of $0.11 previously described. We believe this adjusted guidance represents an achievable range based on a number of assumptions including our ability to manage the balance between volume and pricing during a rising steel

price environment. Additionally, we are assuming that our favorable quoting activity will translate into a strong April 2008 backlog consistent with our adjusted full-year guidance. We expect to update our full-year guidance at the time we report our second-quarter results when we have assessed the market drivers that will impact the second half of fiscal 2008.”

Outlook

Mr. Chambers concluded, “We expect to continue enhancing our ability to produce further profitable growth in difficult market conditions through technology-driven improvements in operating efficiencies. We have achieved steady progress with our major ongoing technology initiatives, such as the engineering systems integration initiative made possible by the RCC acquisition, our Oracle 11i implementation and our web-based order entry system. In addition to these investments, we have also continued to strengthen our financial position including additional debt reduction during the first quarter. As the leading provider of metal buildings and components, we expect our consistent focus on strategies that produce long-term growth in earnings and shareholder value will enable us to continue to outperform our industry throughout the economic cycle.”

NCI will provide an online, real-time webcast and rebroadcast of its conference call tomorrow to discuss this announcement. The live broadcast of this conference call will be available online atwww.ncilp.com orwww.earnings.com beginning at 10:30 a.m. (Eastern Time) on Tuesday, March 4, 2008.
