Item 2.02. Results of Operations and Financial Condition.

On November 6, 2019, Cornerstone issued a press release (the “Press Release”) announcing Cornerstone’s financial results for the fiscal quarter ended September 28, 2019. A copy of the Press Release is attached as Exhibit 99.1.

Additionally, attached hereto as Exhibit 99.2 is a supplemental operational and financial presentation with the results for the fiscal quarter ended September 28, 2019 (the “Supplemental Presentation”). The Supplemental Presentation will be posted on the company’s website, www.cornerstonebuildingbrands.com, on November 6, 2019.

Cornerstone’s Press Release and Supplemental Presentation include Adjusted EBITDA, Adjusted Operating Income, Adjusted Net Income (Loss) Applicable to Common Shares, and Adjusted Net Income (Loss) Per Diluted Common Share, which are non-GAAP financial measures. Adjusted EBITDA excludes restructuring and impairment charges, strategic development and acquisition related costs, loss (gain) on disposition of business, acceleration of CEO retirement benefits, gain on insurance recovery, non-cash gain on foreign currency transactions, loss on extinguishment of debt, non-cash charges of purchase price allocation to inventory, customer inventory buybacks, and share-based compensation. Adjusted Operating Income excludes restructuring and impairment charges, strategic development and acquisition related costs, loss (gain) on disposition of business, acceleration of CEO retirement benefits, gain on insurance recovery, non-cash charges of purchase price allocation to inventory, and customer inventory buybacks. Adjusted Net Income (Loss) Applicable to Common Shares and Adjusted Net Income (Loss) Per Diluted Common Share exclude restructuring and impairment charges, strategic development and acquisition related costs, loss (gain) on disposition of business, loss on extinguishment of debt, acceleration of CEO retirement benefits, gain on insurance recovery, non-cash gain (loss) on foreign currency transactions, non-cash charges of purchase price allocation to inventory, customer inventory buybacks, and the tax effect of the applicable non-GAAP adjustments. Adjusted EBITDA is calculated based on the terms contained in Cornerstone’s term loan credit agreement.

Adjusted EBITDA, Adjusted Operating Income, Adjusted Net Income (Loss) Applicable to Common Shares, Adjusted Net Income (Loss) Per Diluted Common Share are measures used by management and, therefore, provided to investors to provide comparability between periods of underlying operational results. Adjusted EBITDA, Adjusted Operating Income, Adjusted Net Income (Loss) Applicable to Common Shares, Adjusted Net Income (Loss) Per Diluted Common Share should not be considered in isolation or as substitutes for net income (loss), operating income (loss), net income (loss) applicable to common shares, net income (loss) per diluted common share or revenue determined in accordance with generally accepted accounting principles in the United States. The non-GAAP financial measures and reconciliations thereof to the most directly comparable measures prepared in accordance with generally accepted accounting principles are included in the Press Release furnished as Exhibit 99.1 hereto and the Supplemental Presentation attached hereto as Exhibit 99.2.

The information in this Item 2.02, and in Exhibit 99.1 and Exhibit 99.2 which are attached to this Form 8-K shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that Section, nor shall they be deemed incorporated by reference in any registration statement or other filing under the Securities Act of 1933, as amended, or the Exchange Act, except in the event that Cornerstone expressly states that such information is to be considered “filed” under the Exchange Act or incorporates it by specific reference in such filing.

Third Quarter 2019 Results

CARY, NC, November 6, 2019 - Cornerstone Building Brands, Inc. (NYSE: CNR) (the “Company”), the largest manufacturer of exterior building products in North America, today reported financial results for the quarter ended September 28, 2019.

Financial and Operational Highlights for the Third Quarter:

•Net sales of $1,285.0 million

•Gross profit of $309.8 million, or 24.1% of net sales

•Net income of $25.2 million with basic and diluted earnings per share of $0.20

•Adjusted EBITDA of $180.8 million,or 14.1% of net sales

•Net debt leverage reduction from 6.2x to 5.9x in the quarter

Strategic Highlights for the Third Quarter:

•Realized 240 basis point expansion in gross profit margin to 24.1% compared to 21.7% in the pro forma prior year period

•Achieved the expected merger synergies and cost initiatives during the quarter bringing the 2019 year-to-date total to $72.0 million of realized savings

Commenting on the Company’s third quarter performance, Cornerstone Building Brands’ Chairman and Chief Executive Officer, James S. Metcalf said, “During the third quarter, our operational initiatives including procurement, continuous improvement, cost initiatives and merger savings drove significant margin expansion across our windows, siding and commercial businesses, despite lower year-over-year market volumes. With a concentration on pricing discipline and cost management, we were able to successfully deliver a strong quarter at the upper end of our Adjusted EBITDA guidance range.”

“We also generated $97.7 million in operating cash flows for the quarter, which allowed the Company to pay down a net $50.0 million on our ABL facility. By de-levering and strengthening the balance sheet, the improvements actioned and delivered by our cost savings programs are exceeding expectations. Operationally, we remain focused on providing a premier level of quality and service with a broad suite of building products solutions to all our customers,” Mr. Metcalf concluded.

Third Quarter 2019 Results

In December 2018, the Company announced a change to its fiscal year end from a 52/53 week year ending in October to a four-four-five week calendar year end reporting structure. As a result of this change and the merger with Ply Gem, which was completed on November 16, 2018 (the “Ply Gem Merger”), the financial results for the third quarter 2019 are not directly comparable to the third quarter of fiscal year 2018.

Consolidated net sales in the three months ended September 28, 2019 were $1,285.0 million, compared to $548.5 million in the three months ended July 29, 2018. The year-over-year improvement was primarily driven by the additional net sales from Ply Gem and Environmental StoneWorks (“ESW”), which was acquired on February 20, 2019.

Gross profit was $309.8 million in the three months ended September 28, 2019, compared to $133.4 million in the three months ended July 29, 2018. Gross profit margins were 24.1% in the three months ended September 28, 2019, compared to 24.3% in the three months ended July 29, 2018.

Selling, general and administrative (“SG&A”) expenses were $154.0 million in the three months ended September 28, 2019 compared to $79.0 million in the three months ended July 29, 2018. The increase in SG&A expense reflects the additions of Ply Gem and ESW. As a percentage of net sales, SG&A expenses were 12.0% in the three months ended September 28, 2019 compared to 14.4% in the three months ended July 29, 2018.

Operating income in the three months ended September 28, 2019 was $95.6 million, compared to operating income of $54.5 million in the three months ended July 29, 2018. Operating income in the 2019 period reflects the additions of Ply Gem and ESW in the three months ended September 28, 2019 offset by $42.3 million in increased amortization expense associated with the intangibles from the Ply Gem Merger and the ESW acquisition, $10.5 million of additional strategic development and acquisition related costs, and $5.0 million of additional restructuring and impairment charges. Adjusted Operating Income, a non-GAAP financial measure which excludes certain items, was $112.9 million in three months ended September 28, 2019, compared to $52.0 million in the three months ended July 29, 2018.

Net income applicable to common shares in the three months ended September 28, 2019 was $24.8 million, or $0.20 per diluted common share, compared to $35.8 million, or $0.54 per diluted common share in the three months ended July 29, 2018. Net income was impacted by the special items mentioned above for operating income, partially offset by the $4.8 million tax effect associated with these items. Excluding the impact of these special items, Adjusted Net Income, a non-GAAP measure, was $38.0 million, or $0.30 per diluted common share in the three months ended September 28, 2019, compared to $34.1 million, or $0.51 per diluted common share, in the three months ended July 29, 2018.

Adjusted EBITDA, a non-GAAP financial measure, defined in accordance with the Company's credit agreement as earnings before interest, taxes, depreciation and amortization, and certain other cash and non-cash items, was $180.8 million in the three months ended September 28, 2019, compared to $63.5 million in the three months ended July 29, 2018. Please see the reconciliations of Adjusted Operating Income, Adjusted Net Income and Adjusted EBITDA to the nearest financial measures prepared in accordance with GAAP in the accompanying financial tables.

Cash and cash equivalents as of September 28, 2019 were $105.2 million. As of September 28, 2019, the Company had $170.0 million drawn on its $611.0 million asset-based lending (“ABL”) facility reflecting $50.0 million in net payments made during the three months ended September 28, 2019.

Third Quarter 2019 Segment Performance

Net sales in the Windows segment were $504.3 million during the three months ended September 28, 2019, which included $108.8 million attributable to Silver Line. Ply Gem’s acquisition of a portfolio of products sold under the Silver Line and American Craftsman brands, certain manufacturing plants and associated distribution and support services was completed on October 14, 2018. Gross profit in the three months ended September 28, 2019 was $98.3 million. As a percent of net sales, the Windows segment’s gross profit was 19.5%. Operating income was $34.4 million in the three months ended September 28, 2019.

The Siding segment generated $315.8 million in net sales during the three months ended September 28, 2019, which included $45.4 million from ESW. Gross profit in the three months ended September 28, 2019 was $90.6 million and 28.7% as a percent of net sales. Operating income was $37.1 million in the three months ended September 28, 2019.

Net sales in the Commercial segment were $464.9 million in the three months ended September 28, 2019 compared to $548.5 million in the three months ended July 29, 2018. The year-over-year decrease was primarily a result of lower industry volumes. Gross profit was $120.9 million in the three months ended September 28, 2019, compared to $133.4 million in the three months ended July 29, 2018. As a percent of net sales, gross profit was 26.0%, an increase of 170 basis points, compared to 24.3% in the three months ended July 29, 2018. The increase was driven by pricing discipline combined with benefits from cost reduction initiatives and merger synergies. Operating income was $59.3 million during the three months ended September 28, 2019, compared to $80.0 million in the three months ended July 29, 2018. Operating income in the current three months ended September 28, 2019 was impacted by a change to the allocation of costs that had previously been in Corporate to the Commercial segment.

Guidance

The Company’s key economic indicators are tracking toward low growth in the residential new construction and repair & remodel markets and a moderate contraction in the commercial construction markets. Based on these market indicators and the synergies and cost initiatives, the Company expects Adjusted EBITDA to be in the range of $135 to $150 million for the fourth quarter of fiscal 2019.
