Norman C. Chambers, Chairman and Chief Executive Officer, commented, "We are pleased to deliver another quarter of strong performance with year-over-year growth in our revenues, gross margins and Adjusted EBITDA. The positive results were driven by our solid platform of manufacturing and supply chain initiatives, combined with ongoing strong commercial focus and discipline. While we have seen modest growth in nonresidential construction, NCI's third quarter performance significantly outpaced our markets. NCI's underlying tonnages volumes were up 11.6% year-over-year, and each of our three business segments delivered both top line growth and bottom line margin expansion."

Third quarter 2016 sales increased to $462.4 million, or 9.9%, from $420.8 million in last year's third quarter, due mainly to increased volumes across all three segments. Similar to the prior three quarters, the pass-through of lower year-over-year steel costs detracted from revenue growth, while underlying volumes and margins showed continued year-over-year improvement.

Gross profit increased 27.1% to $128.0 million from $100.7 million in the third quarter of 2015, and gross profit margin expanded 380 basis points to 27.7%, compared to 23.9% in the prior year period. Improved margin performance during the quarter was driven largely by increased operating leverage from higher volumes complemented by a continued focus on commercial discipline, supply chain effectiveness and manufacturing efficiency.

Engineering, selling, general and administrative (ESG&A) expenses increased 7.9% to $80.4 million from $74.5 million in the third quarter of 2015 due largely to higher incentive compensation charges on improved operating

results and higher selling costs resulting from increased volume. As a percentage of revenues, ESG&A expenses decreased to 17.4% in the 2016 third quarter compared to 17.7% in the prior year's period.

Operating income increased to $43.5 million, compared to $19.4 million in the prior year's third quarter. Excluding the special items noted below, Adjusted Operating Income, a non-GAAP measure, increased 79.2% to $45.1 million in the current quarter from $25.2 million in the third quarter of 2015 due to the expansion in revenues and gross profit margins.

Third quarter 2016 net income increased 229.0% to $23.6 million, or $0.32 per diluted common share, compared to

$7.2 million, or $0.10 per diluted share in the prior year third quarter. Net income included $1.0 million of special charges comprised of $0.1 million of acquisition related costs pertaining to completed acquisitions, $0.7 million of cost related to the July 2016 Secondary Offering (as defined below) and Stock Repurchase (as defined below), $0.8 million of restructuring and severance costs, offset by the related tax effect of $0.6 million for these items. The third quarter of 2015 included $3.6 million of similar special charges, net of tax. Excluding these special items, Adjusted Net Income for the third quarter increased 127.7% to $0.33 per diluted common share compared to $0.15 in the prior year third quarter.

Adjusted EBITDA, a non-GAAP measure, defined in accordance with the Company's term loan credit agreement as earnings before interest, taxes, depreciation and amortization, and other cash and non-cash items, was $57.8 million, up 51.4% from $38.2 million in the prior year's third quarter. Adjusted EBITDA margins expanded 340 basis points to 12.5% from 9.1 % in 2015. Fiscal year-to-date, Adjusted EBITDA has increased 53.6%, over the same period in the prior year. Please see the reconciliation of Adjusted Operating Income, Adjusted EBITDA and Adjusted Net Income in the accompanying financial tables.

Cash and cash equivalents at quarter's end was $50.7 million compared to $48.3 million at the comparable period end in fiscal 2015 and compared sequentially to $77.9 million at the end of the second quarter of fiscal 2016. The Company paid down an additional $10 million on its term loan in the third quarter of fiscal 2016, and expects to make total debt repayments of $40 million during the current fiscal year. Also, concurrent with the registered underwritten public offering (the "Secondary Offering") by funds affiliated with Clayton, Dubilier & Rice LLC (the "CD&R Funds"), NCI entered into a separate agreement to repurchase $45 million of its common stock from the CD&R Funds in a private transaction (the "Share Repurchase"), at the offering price less the underwriting discount. The Company's net debt leverage ratio at the end of the third fiscal quarter improved to 2.2x from net leverage of 3.4x in the prior year period end. In addition, the Company's $150.0 million asset based lending facility remained undrawn as of July 31, 2016.

Third party sales in the Buildings segment increased slightly to $175.5 million in the third quarter from $172.2 million in the prior year quarter, primarily due to increased volumes offset by the pass-through of lower steel cost. Operating income increased 36.2% to $19.6 million in the current quarter, compared to $14.4 million in the third quarter of fiscal 2015. Adjusted Operating Income increased 35.3% to $19.6 million in the current quarter, compared to $14.5 million in the third quarter of fiscal 2015. The improved margins in the Buildings segment were driven by strong commercial discipline, operating leverage and effective supply chain management.

The Components segment generated $256.2 million in third-party sales during the quarter, an increase of 15.4% from $222.0 million in the third quarter of fiscal 2015, with strength in both the traditional metal component product lines and the insulated metal panel products. Operating income increased 120.2% to $37.5 million in the current quarter, compared to $17.0 million in the third quarter of fiscal 2015. Adjusted Operating Income increased to $37.8 million from $21.6 million in the same quarter last fiscal year. The Components segment's profitability benefited

from a combination of strong commercial discipline and effective supply chain management, as well as an improving product mix in insulated metal panels.

Third party sales in the Coatings segment were $30.7 million, a 15.3% increase from $26.6 million in last year's third quarter. Operating income increased 59.1% to $8.7 million in the current quarter, compared to $5.5 million in the third quarter of fiscal 2015. Adjusted Operating Income increased 59.1% to $8.7 million in the third quarter of fiscal 2016, compared to $5.5 million reported in the same period last year. The Coatings segment's operating income improvement was driven primarily by increased operating leverage on higher total volumes processed.

Current market data from internal bookings reflects several end-market segments showing year-over-year positive growth including agricultural, commercial warehouse, retail, government, religious buildings and transportation. Geographic markets demonstrating year-over-year growth include East, South Central, Mountain, New England, and Pacific areas of the United States.

The combination of leading indicators that the Company continues to track includes residential starts (a 13-month lag); the American Institute of Architects Billings Index for mixed practices (a 13-month lag) and the Conference Board's Leading Economic Index (a 9-month lag). The indicators, as a group, have historically had a very strong correlation with Dodge (low-rise) nonresidential new construction starts. Based on these leading indicators, the Company continues to expect positive growth of 4.0% - 6.0% in low-rise nonresidential new construction starts during fiscal year 2016.

For the full year, NCI continues to expect 2016 to be a better year than 2015 in terms of revenues, gross margin and Adjusted EBITDA. Due to the rapidly rising material costs, management believes that some customers, particularly in the Components segment, may have accelerated project deliveries into the third quarter to avoid expected price increases. This dynamic has already been included in management's previously announced outlook for the fiscal year and it does not change the Company's expectations for the fiscal fourth quarter and full-year results. However, it is expected to produce a somewhat muted sequential increase from the fiscal third quarter to fiscal fourth quarter results, as compared to the Company's historical seasonal pattern.

The Company has provided detailed financial guidance in the quarterly supplemental presentation at www.ncibuildingsystems.com under the "Investors" section and continues to expect that the fiscal 2016 fourth quarter results to be broadly in-line with this year's fiscal third quarter.
