Herndon, Virginia, November 4, 2015. Continental Building Products, Inc. (NYSE: CBPX) (the Company), a leading manufacturer of wallboard and gypsum-based products, announced today results for the third quarter ended September 30, 2015.

Highlights of Third Quarter 2015 as Compared to Third Quarter 2014

• Net sales of $108.2 million, compared to $113.8 million

• Gross margin grows 310 basis points to 27.7%

• Adjusted EBITDA¹ essentially flat at $33.7 million

• Adjusted earnings per share¹ of $0.25 compared to $0.22. GAAP earnings per share of $0.10 compared to $0.22.

• Repurchased approximately $20.0 million of common stock in the third quarter and approximately $40.0 million during nine month period ended September 30, 2015

• Reduced debt by $15.0 million in the third quarter and $35.0 million during nine month period ended September 30, 2015

“In the third quarter we delivered Company record Adjusted EBITDA margin and Adjusted Cash Flow from Operations¹ attributed to our efficient, low cost position despite softer demand in our primary markets east of the Mississippi,” stated Jay Bachmann, Continental’s Chief Executive Officer. “To that end, we delivered a 7.2% increase in gross profit and 310 basis point improvement in gross margin compared to a year ago. Furthermore, for the second consecutive quarter we deployed cash to repurchase approximately two percent of our outstanding shares for $20.0 million while also reducing our debt. As we move into the end of 2015, the long-term underlying fundamentals for improvement in our business remain positive. While we cannot control near-term end market fluctuations, we believe our strategy and low cost, high cash flow operations position us to take advantage of value-enhancing opportunities including the stock repurchase program announced today.”

The Company announced today that its Board of Directors has authorized a stock repurchase program under which the Company may repurchase shares of its outstanding common stock up to an aggregate amount of $50.0 million through the end of 2016.

Dennis Schemm, Chief Financial Officer, stated “this stock repurchase program is a continued demonstration of confidence in our attractive business model and commitment to delivering shareholder value. With our strong cash flow generation we are well positioned to bolster our business while decreasing debt and enhancing shareholder returns.”

Third Quarter 2015 Results vs. Third Quarter 2014

Net sales for the third quarter of 2015 were $108.2 million, compared to $113.8 million in the third quarter of 2014. Wallboard volumes of 567 million square feet (MMSF) were down (3.9%) compared to 590 MMSF in the prior year quarter, mainly driven by a slower market. The average mill net price² was $153.05 per MSF, down (0.7%) compared to $154.10 per MSF in the prior year quarter, mainly due to weaker Canadian dollar and regional sales mix. At constant currency, average mill net price increased 0.5% compared to the prior year quarter. For US shipments, the average mill net price was slightly favorable compared to the prior year quarter.

Gross profit was $30.0 million, an increase of 7.2% compared to $28.0 million in the prior year quarter. The gross margin of 27.7% expanded from 24.6% in the prior year quarter, primarily as a result of strict cost controls and favorable energy costs.

Selling and administrative (SG&A) expense was $9.0 million, compared to $7.8 million in the prior year quarter. The increase was largely due to additional amortization of software development costs of $0.4 million, professional fees of $0.2 million incurred in connection with secondary common stock offering costs in September 2015 and $0.6 million related to additional costs of being a public company.

The expense associated with the Company’s Long Term Incentive Plan, which was implemented and is funded by Lone Star (LTIP), was $9.9 million for the third quarter of 2015. Certain members of the Company’s management team earned payments under the LTIP in connection with Lone Star’s sale of common stock in the September secondary public offering.

Operating income was $11.1 million, compared to $20.2 million in the prior year quarter, mainly due to the LTIP expense in the third quarter of 2015, with no comparable expense in the prior year quarter. Excluding the expense associated with the LTIP, operating income increased 3.9% to $21.0 million, compared to the prior year quarter.

Interest expense was $4.2 million, an improvement of $0.7 million from $4.9 million in the prior year quarter, reflecting a reduction in the long-term debt and a decrease in the interest rate on the Company’s borrowings.

Adjusted net income¹ grew to $10.7 million, or $0.25 per share, compared to adjusted net income of $9.5 million, or $0.22 per share, in the prior year quarter. GAAP net income was $4.2 million, or $0.10 per share, compared to net income of $9.5 million, or $0.22 per share, in the prior year quarter.

Adjusted EBITDA was essentially flat at $33.7 million compared to the prior year quarter. Adjusted EBITDA as a percentage of net sales was 31.1% compared to 29.6% in the prior year quarter.

Balance Sheet and Cash Flow

At the end of the quarter on September 30, 2015, the Company had cash of $17.3 million and total debt outstanding of $314.5 million. In the third quarter of 2015, the Company generated cash flow from operations of $28.4 million and incurred $1.4 million of capital expenditures and software development costs. Excluding the net impact of the LTIP, the Company produced adjusted cash flow from operations¹ of $38.3 million in the third quarter of 2015, an improvement of $4.9 million over the prior year.

²  Mill net price represents average selling price per thousand square feet (MSF), net of freight and delivery costs.

In the third quarter of 2015, the Company repurchased approximately 1,007,500 shares of its common stock at an aggregate purchase price of $20.0 million from an affiliate of Lone Star in a private, non-underwritten transaction in connection with the secondary public offering in September 2015. In the third quarter of 2015, the Company also used cash flow from operations for the voluntary repayment of $15.0 million of debt with the next principal payment on the Company’s debt not due until August 2020.

Reconciliation of GAAP Measures to Non-GAAP Measures

EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Earnings Per Share, and Adjusted Cash Flow from Operations have been presented in this press release as supplemental measures of financial performance that are not required by, or presented in accordance with, Generally Accepted Accounting Principles (GAAP). This release presents EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Earnings Per Share, and Adjusted Cash Flow from Operations as supplemental performance measures because management believes that they facilitate a comparative assessment of the Company’s operating performance relative to its performance based on results under GAAP while isolating the effects of some items that vary from period to period without any correlation to core operating performance and eliminate certain charges that management believes do not reflect the Company’s operations and underlying operational performance. Management also believes that EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Earnings Per Share, and Adjusted Cash Flow from Operations are useful to investors because they present a better reflection of the Company’s performance as an independent company following the acquisition of the business from Lafarge North America and allow investors to view the business through the eyes of management and the Board of Directors, facilitating comparison of results across historical periods.

EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Earnings Per Share, and Adjusted Cash Flow from Operations may not be comparable to similarly titled measures of other companies because other companies may not calculate EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Earnings Per Share, and Adjusted Cash Flow from Operations in the same manner. EBITDA, Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Earnings Per Share, and Adjusted Cash Flow from Operations are not measurements of the Company’s financial performance under GAAP and should not be considered in isolation or as alternatives to operating income, net income, earnings per share or cash flow from operations determined in accordance with GAAP or any other financial statement data presented as indicators of financial performance or liquidity, each as calculated and presented in accordance with GAAP.

The following is a reconciliation of operating income to EBITDA, Adjusted EBITDA and Adjusted EBITDA margin:
