NCI Building Systems Reports Strong

Fourth Quarter and 2015 Fiscal Year End Results

HOUSTON, December 10, 2015 – NCI Building Systems, Inc. (NYSE: NCS) (“NCI” or the “Company”) today reported financial results for the fourth quarter and fiscal year ended November 1, 2015.

Fourth Quarter 2015 Financial and Operational Highlights:

Fiscal 2015 Financial and Operational Highlights:

*Defined as Adjusted EBITDA – net capital expenditures + changes in net working capital

Norman C. Chambers, Chairman, President and Chief Executive Officer, commented, “We are pleased to have delivered on our commitment to increase gross profit margin and Adjusted EBITDA, marking the sixth consecutive quarter of year-over-year improvement. Our solid fourth quarter results helped us achieve the best second half and full year performance since 2008. The improved performance across all three operating segments is a direct result of the reorganization of our business and strategic initiatives implemented over the past few years. Specifically, our fiscal 2015 performance delivered a 59% increase in net income and a 72% increase in Adjusted EBITDA. In addition, despite continued choppy market conditions, we have been able to deliver earnings growth over the prior several quarters through increased volumes, commercial discipline, and manufacturing improvements.”

Fourth Quarter 2015 Results

Fourth quarter 2015 sales increased to $459.8 million, or 17.2%, from $392.4 million in last year's fourth quarter, due mainly to increased volumes across all three segments and the impact of the CENTRIA acquisition. The legacy single skin and insulated metal panel (IMP) product lines, as well as the Buildings group, delivered strong results.

Gross profit increased 32.3% to $123.6 million from $93.4 million in the fourth quarter of 2014, while gross profit margin expanded 310 basis points to 26.9%, compared to 23.8% in the prior year period. The improved margin performance was driven largely by a combination of commercial discipline, effective supply chain initiatives and the impact of the operating leverage created by increased utilization.

Engineering, selling, general and administrative (ESG&A) expenses increased 13.5% to $76.4 million from $67.3 million in the fourth quarter of 2014 due largely to the CENTRIA acquisition and, to a lesser extent, increased incentive compensation. As a percentage of revenues, ESG&A expenses decreased approximately 60 basis points to 16.6% in the 2015 fourth quarter compared to 17.2% in the prior year’s period.

Adjusted operating income, a non-GAAP measure, increased 74.7% to $43.8 million in the current quarter from $25.1 million in the fourth quarter of 2014, driven by the expansion in gross profit margin. On a GAAP basis, operating income increased to $36.5 million, or 69.2%, compared to $21.6 million in the prior year’s fourth quarter and increased 88.4% sequentially from the third quarter of fiscal 2015.

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 cash and other non-cash items, was $56.4 million, up 55.6% from $36.3 million in the prior year’s fourth quarter. This performance marks a continuation from the third quarter, in which Adjusted EBITDA increased 53.0% year-over-year.

Fourth quarter 2015 net income was $18.4 million, or $0.25 per diluted common share, and was impacted by the following items: $7.6 million of restructuring and impairment charges; $1.1 million of strategic development and acquisition related costs pertaining to acquisitions that have been completed; $2.3 million of amortization of short lived intangibles and $3.8 million gain on legal settlements. Excluding the impact of these special items, the Company reported adjusted net income applicable to common shares, a non-GAAP measure, of $22.7 million, or $0.31 per diluted common share, compared to $13.8 million, or $0.19 per diluted common share, in the fourth quarter of 2014.

During the fourth quarter, NCI developed plans to improve cost efficiency by optimizing our manufacturing footprint through the integration of operations from our recent acquisitions, which resulted in the recognition of certain asset impairment charges. The Company believes that the successful execution of these improvement plans over the next 12-36 months will result in annualized cost savings of $15-20 million.

Interest expense increased to $8.0 million in the fourth quarter of 2015, compared to $3.1 million in last year’s fourth quarter as a result of the $250 million, 8.25% senior notes, issued to finance the CENTRIA acquisition.

Cash and cash equivalents at quarter’s end was $99.7 million compared to $66.7 million in the comparable period in fiscal 2014 and grew sequentially from $48.3 million at the end of the third quarter of fiscal 2015. The Company paid down an additional $10 million under its term loan in the fourth quarter of fiscal 2015, bringing the total debt repayments to $40 million during the fiscal year. NCI’s proforma net debt leverage ratio at the end of the fourth fiscal quarter improved to 2.7x, moving closer to the previous pre-Centria acquisition leverage of 2.2x. In addition, the Company’s $150.0 million ABL facility remained undrawn as of November 1, 2015.

Fourth Quarter 2015 Segment Performance

Third party sales in the Buildings group increased slightly to $192.5 million in the fourth quarter from $189.7 million in the prior year quarter, primarily due to higher volumes from an improved product portfolio mix. Gross profit increased to $58.9 million from $51.4 million in the fourth quarter 2014, and gross profit margin expanded 330 basis points to 29.8%. Adjusted operating income increased 36.3% to $26.4 million in the current quarter, compared to $19.4 million in the fourth quarter of fiscal 2014. The improved margins in the Buildings segment were driven by improvements in commercial discipline, supply chain management and manufacturing efficiencies.

The Components group generated $240.6 million in third-party sales during the quarter, an increase of 41.3% from $170.3 million in the fourth quarter of fiscal 2014, led by CENTRIA’s contribution as well as continued strength of the legacy single skin and roll-up door product lines. Gross profit increased to $56.2 million from $33.9 million in the fourth quarter 2014, while gross profit margin expanded 310 basis points to 20.3%. Adjusted operating income increased to $26.9 million from $14.3 million in the same quarter last fiscal year. The Components segment’s profitability benefited from CENTRIA’s contribution, improved product mix and commercial discipline. During the fourth quarter, CENTRIA contributed $58.3 million in sales and $6.2 million in Adjusted EBITDA.

Third party sales in the Coatings group were $26.7 million, a 17.6% decline from $32.4 million in last year’s fourth quarter. Gross profit decreased slightly to $8.8 million from $8.9 million in the fourth quarter 2014, while gross profit margin increased 110 basis points to 13.8%. Adjusted operating income increased 4.0% to $7.2 million in the fourth quarter of fiscal 2015, compared to $6.9 million reported in the same period last year.

Market Commentary

Current market estimates continue to show subdued activity in nonresidential markets. Nonresidential construction starts, as measured in square feet, were down 7% in fiscal 2015 according to Dodge Data & Analytics. Low-rise starts, comprising buildings one to five stories, were down 6% for fiscal 2015. However, leading indicators for low-rise, nonresidential construction activity continue to indicate positive momentum moving into fiscal year 2016.

The leading indicators with the most meaningful correlation to nonresidential low-rise construction starts are The American Institute of Architects’ (AIA) Architecture Mixed Use Index, Dodge Residential single family starts and the Conference Board Leading Economic Index (LEI). Historically, there has been a very high correlation to the Dodge low-rise nonresidential starts when the three leading indicators are combined and then seasonally adjusted. Currently, the forward projection of these metrics indicates modest growth for the first half of fiscal 2016.

Outlook and Guidance

Mr. Chambers remarked, “Over the last 18 months, we generated substantial improvements in both gross profit margin and Adjusted EBITDA, which was the direct result of a very deliberate strategy led by commercial discipline, effective supply chain management and enhanced manufacturing efficiencies. We will continue to execute on our strategic initiatives to further optimize our manufacturing footprint and decrease our cost structure over the next several quarters as we anticipate low to mid-single digit nonresidential market growth rates in calendar 2016.”

“Our strong backlog includes a greater proportion of higher-complexity projects that have a longer lead time for production, providing us with good visibility through the first half of fiscal 2016. We expect our investments in IMP products over the past several years will help us to further unlock the anticipated growth potential of the underpenetrated North American market. We currently anticipate delivering year-over-year improvement in fiscal 2016. Similar to past years and due to the seasonal nature of our business, we expect our second half performance of fiscal 2016 to be stronger than the first half.”
