NCI Building Systems Reports First Quarter Fiscal 2011 Result

— Q1 Revenues Increased 4.3%; Tonnage up 2.2% —

— Buildings Group Bookings Increased 27% Year-Over-Year;

Backlog Up 6% Sequentially to $205 Million —

HOUSTON, March 8, 2011 /PRNewswire/ — NCI Building Systems, Inc. (NYSE: NCS) today reported financial results for the first quarter ended January 30, 2011.

First Quarter 2011 Financial Results

“First quarter revenue growth was driven by a 10% increase in the combined third party sales of our Coatings and Components groups. This performance was achieved despite a 16% decline in low-rise nonresidential construction activity for the same period, as reported by McGraw-Hill,” said Norman C. Chambers, NCI’s Chairman, President and Chief Executive Officer. “Our Coatings group’s results were especially strong, reflecting the success of our efforts to build external sales to traditional and non-traditional markets, while continuing to base load our facilities with intersegment business. Reduced market volume affected our Buildings group’s shipments, but the group achieved year-over-year bookings and sequential backlog growth of 27% and 6%, respectively, in the first quarter. These results serve as strong indicators that our Buildings group’s performance should improve significantly in the coming periods, particularly in the second half of the fiscal year.”

“Exclusive of special charges incurred in our Components group, operating income for our Coatings and Components groups was comparable to last year’s levels, absorbing the net effect of steel price volatility in the first quarter and the impact of a record number of weather-related work stoppages during the period. There was a modest improvement in our Buildings group’s operating results, but we expect a more meaningful improvement going forward as a result of greater commercial discipline embedded in our current backlog and the growing proportion of work coming from the commercial and industrial markets, which points to increasing demand from our traditional customer base.”

For the first quarter, sales were $190.1 million, up 4.3% from the $182.2 million reported in last year’s first quarter. Gross profit margin was 17.6% compared to 17.8% in the year-ago first quarter.

Selling, general and administrative expenses were $47.7 million, or 25.1% of revenues, inclusive of $1.4 million in special charges and an $884,000 increase in non-cash stock compensation. This compares to $44.6 million, or 24.5% of revenues in last year’s first quarter. The Company incurred an operating loss of $14.1 million this quarter compared to an operating loss of $12.7 million in the prior year period. Adjusted EBITDA, defined as earnings before interest, taxes, depreciation and amortization, and cash and other non-cash items, in accordance with the Company’s bank credit agreement, was negative $4.4 million compared to negative $2.6 million in last year’s first quarter.

For the first quarter, the Company reported a net loss applicable to common shares of $20.7 million, which included the accrual of preferred stock dividends and accretion of $6.2 million and a non-cash beneficial conversion feature charge of $1.8 million. This compares to a net loss of $18.8 million in the 2010 first quarter.

The adjusted loss per diluted common share, excluding the non-cash beneficial conversion charge and other special charges presented in the attached tables, was $0.99; the reported net loss per diluted common share was $1.14. This compares to an adjusted loss per diluted common share of $0.99 and a reported net loss per diluted common share of $1.04 in last year’s first quarter; each adjusted for the 1-for-5 reverse split that was effective at the close of market on March 5, 2010.

The weighted average number of common shares used in the calculation was 18.1 million for both first quarter 2011 and 2010 per share amounts.

Inventory levels increased 2.5% sequentially to $83.4 million, reflecting seasonal factors. Annualized inventory turnover was 7.5 turns for the first quarter compared to 7.3 turns year-over-year and 8.6 turns sequentially.

Capital expenditures were $2.2 million; net cash from operating activities was positive $132,000.

Additional Corporate Developments

For the second consecutive quarter, the Preferred Dividend Committee of the Board of Directors elected to pay the $5.5 million preferred dividend in cash. As a result, we plan to record a dividend accrual reversal of $1.4 million in the second quarter of fiscal 2011. In addition, we plan to record a beneficial conversion feature reversal of $4.2 million in the second quarter of fiscal 2011. The determination of cash payment versus payment in-kind or “PIK” of the preferred dividends will be made each quarter adhering to the limitations of the Company’s term loan and ABL credit facilities as well as the Company’s intermediate and long-term cash flow requirements. The Company’s term loan currently restricts the payment of cash dividends to 50% of cumulative earnings beginning with the fourth quarter of 2009, and in the absence of accumulated earnings, cash dividends and other restricted payments, is limited to $14.5 million in the aggregate during the term of the loan.

First Quarter Segment Performance

The Company reported an adjusted operating loss of $12.8 million, which is reconciled with the reported GAAP operating loss in the table below.

“While each of our business segments continued to be affected by historically low market demand and the typical seasonality associated with our first fiscal quarter, we continue to focus on efficiency improvements throughout the organization designed to streamline operations as our markets recover,” Mr. Chambers said. “We believe that NCI’s vertically integrated business model

provides us with important competitive advantages that we can leverage as economic conditions improve.”

Revenues for the Coatings group increased 8.3% year-over-year, reflecting successful marketing efforts in both traditional and non-traditional markets, as well as an increase in orders in advance of steel price increases. Operating income increased 10.4%. Once operational, the recently purchased sixth Coatings plant in Middletown, Ohio will support future growth in third party sales and internal demand from the Components and Buildings groups as well as significantly increase the Coatings group’s footprint in an area of the country with important growth potential.

The Components group’s revenues increased 4% from last year’s first quarter levels. In addition to special charges, lower selling prices caused margin compression compared to last year’s first quarter. The Components group increased sales of retrofit roofing products and energy-efficient insulated metal panels in the quarter, and work has already begun on re-tooling two of the Company’s previously idled facilities to capitalize on increasing demand for energy efficient insulated metal panels.

The Buildings group’s revenues were comparable with first quarter 2010 levels and operating results improved modestly despite lower volume. Investments in manufacturing efficiencies and significant upgrades to engineering and drafting systems across all brands have positioned this group for improved results as market demand strengthens.

Market Commentary

In the first fiscal quarter of 2011, low-rise nonresidential construction activity measured in square feet declined 16% from the comparable period in fiscal 2010, as reported by McGraw-Hill.

The American Institute of Architect’s Architectural Billing Index published for January was 50.0 and the commercial and industrial component of the Index remained above 50 for the seventh consecutive month.

McGraw-Hill is currently forecasting that nonresidential construction activity measured in square feet will be 7% higher in calendar 2011 compared to calendar 2010, with most of the improvement occurring in the second half of the year. McGraw-Hill projects CY 2011 square footage at 695 million, up from 650 million in 2010.

Summary and Outlook

“The pick-up in quoting activity that we signaled at the end of fiscal 2010 continued in the first quarter. We are particularly encouraged by the 27% increase in bookings in the first fiscal quarter and by the higher proportion of bookings and backlog represented by commercial/industrial work, which prior to the economic downturn had accounted for 70% of our business. A sustained upturn in this sector would significantly benefit NCI in future periods as we have retained the capacity to serve a much larger marketplace with significantly reduced infrastructure costs,” Mr. Chambers noted.

“In the meantime, we continue to enhance our competitive position by working diligently to roll-out new sales initiatives, implement technical upgrades to increase efficiencies and train our employees on new systems that will further improve customer service levels and reduce operating costs.”
