CHICAGO – February 14, 2019 – USG Corporation (NYSE:USG), an industry-leading manufacturer of building products and innovative solutions, today reported financial results for the fourth quarter and full year of 2018.

• Net income of $42 million up $111 million, or 161%

Non-GAAP financial measures for 2018’s fourth quarter as compared to 2017’s fourth quarter are below:

• Adjusted operating profit of $55 million down $45 million, or 45%

• Adjusted net income of $37 million down $40 million, or 52%

• Net sales of $3.3 billion up $132 million, or 4%

• Operating profit of $227 million down $126 million, or 36%

• Net income of $196 million up $108 million, or 123%

• Adjusted net income of $218 million down $46 million, or 17%

• Adjusted diluted EPS of $1.51 down $0.29, or 16%

Consolidated Results

Fourth quarter 2018 net sales were $819 million on a consolidated basis, compared to $831 million in the fourth quarter of 2017. Operating profit decreased to $37 million from $83 million, while adjusted operating profit decreased to $55 million from $100 million in the fourth quarter of 2018 compared to the fourth quarter of 2017. The lower operating profit in the fourth quarter of 2018 was driven primarily by lower sales partially due to the comparative timing of announced wallboard price increases and associated lack of pre-buy in the fourth quarter of 2018, higher costs across each of our segments, and higher planned selling and administrative expenses to support USG’s Customer- First strategy.

USG recorded $42 million in net income, or $0.30 per diluted share, for the fourth quarter of 2018, compared to a net loss of $69 million, or ($0.49) per diluted share, in the fourth quarter of 2017. The net loss in the fourth quarter of 2017 includes $145 million of income tax expense resulting from the Tax Cuts and Jobs Act. On an adjusted basis, net income of $37 million, or $0.26 per diluted share, for the fourth quarter of 2018 decreased from $77 million, or $0.53 per diluted share, in the fourth quarter of 2017.

USG recorded full year 2018 net sales of $3.3 billion, net income of $196 million, and diluted earnings per share of $1.38 compared to net sales of $3.2 billion, net income of $88 million and diluted earnings per share of $0.60 in 2017. On an adjusted basis, the Company generated full year 2018 net income of $218 million, or diluted earnings per share of $1.51. For comparative purposes, on an adjusted basis, USG recorded net income of $264 million, or diluted earnings per share of $1.80, for the full year of 2017. A full reconciliation of GAAP to adjusted metrics is provided in the attached schedule.

U.S. Wallboard & Surfaces

The U.S. Wallboard & Surfaces segment net sales for the fourth quarter of 2018 decreased $12 million, or 2%, compared with the fourth quarter of 2017. The segment generated $54 million of operating profit in the fourth quarter of 2018 compared to operating profit of $78 million in the fourth quarter of 2017. On an adjusted basis, operating profit of $54 million decreased by $24 million compared to the fourth quarter of 2017. Wallboard volumes decreased 8% compared to the fourth quarter of 2017, outpacing industry volumes by 2%. Wallboard price increased 5% from the fourth quarter of 2017 due primarily to January 2018 and June 2018 price increases. However, wallboard costs were $18 million higher than the prior year quarter primarily due to higher input costs, which were partially offset by $5 million in cost savings in the fourth quarter 2018 due to the Company’s Advanced Manufacturing initiative.

U.S. Performance Materials

The U.S. Performance Materials segment net sales decreased by $1 million, or 1%, compared with the fourth quarter of 2017 due to lower shipments, which was partially offset with higher average realized selling prices. The segment generated $2 million of operating loss in the fourth quarter of 2018 compared to operating profit of $4 million in the fourth quarter of 2017. On an adjusted basis, operating loss of $2 million declined by $6 million compared to the fourth quarter of 2017 primarily due to higher input costs and SG&A investments to accelerate the future adoption of new products.

U.S. Ceilings

The U.S. Ceilings segment net sales decreased $1 million, or 1%, compared to the fourth quarter of 2017. The segment generated $12 million of operating profit in the fourth quarter of 2018 compared to operating profit of $24 million in the fourth quarter of 2017. On an adjusted basis, operating profit of $15 million decreased by $9 million from the fourth quarter of 2017, primarily due to lower volumes and higher costs across tile and grid products, which was partially offset by higher realized average selling prices.    

USG Boral

USG Boral net sales decreased $20 million, or 6%, compared to the fourth quarter of 2017. The decrease is primarily due to the unfavorable impact of currency translation of $14 million and lower wallboard shipments. The segment generated $9 million of equity income in the fourth quarter of 2018, which is a $8 million decrease compared to the fourth quarter of 2017 primarily due to a reduction in sales coupled with higher input costs.

Pending Knauf and USG Merger

On June 11, 2018, Gebr. Knauf KG (Knauf) and USG announced that they had entered into a definitive merger agreement pursuant to which Knauf will acquire all the outstanding shares of USG. Under the terms of the merger agreement, USG stockholders will receive $44 per share, which consists of $43.50 per share in cash payable upon

closing of the transaction and a $0.50 per share conditional special dividend that was paid on October 2, 2018, following stockholder approval of the transaction. The transaction is expected to close in early 2019, subject to customary closing conditions, including receipt of regulatory approvals.

Fourth Quarter 2018 Conference Call

In light of the announced transaction with Knauf, the Company will not hold a conference call for its results for the fourth quarter and full year 2018. The Company plans to file its Annual Report on Form 10-K for the full year with the SEC on or about February 14, 2019.

Non-GAAP Financial Measures

In this press release, the Company’s financial results are provided both in accordance with accounting principles generally accepted in the United States of America (GAAP) and using certain non-GAAP financial measures. In particular, the Company presents the non-GAAP financial measures adjusted net sales, adjusted operating profit, adjusted net income, adjusted selling and administrative expenses, EBITDA, adjusted EBITDA, adjusted diluted earnings per share, and impacts of foreign currency on current period results using prior period translation rates, which exclude certain items. The non-GAAP financial measures are included as a complement to results provided in accordance with GAAP because management believes these non-GAAP financial measures help investors’ ability to analyze underlying trends in the Company’s business, evaluate its performance relative to other companies in its industry and provide useful information to both management and investors by excluding certain items that may not be indicative of the Company’s core operating results. Adjusted operating profit on a consolidated basis includes the equity method income from USG Boral because management views USG Boral as an important business. In addition, the Company uses adjusted operating profit and adjusted net income as components in the measurement of incentive compensation. The non-GAAP measures should not be considered a substitute for or superior to GAAP results and may vary from others in the industry. For further information related to the Company’s use of non-GAAP financial measures, and the reconciliations to the nearest GAAP measures, see the schedules attached hereto.

Cautionary Statements

This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 related to management’s expectations about future conditions, including but not limited to, statements regarding the proposed transaction with Knauf (the “merger”), including expected timing and completion of the merger. Actual business, market or other conditions may differ materially from management’s expectations and, accordingly, may affect the Company’s sales and profitability, liquidity and future value. Any forward-looking statements represent the Company’s views only as of today and should not be relied upon as representing the Company’s views as of any subsequent date, and the Company undertakes no obligation to update any forward-looking statement. Among the risks, contingencies and uncertainties that could cause actual results to differ from those described in the forward-looking statements or could result in the failure of the merger to be completed are the following: the failure to obtain necessary regulatory or other governmental approvals for the merger, or if obtained, the possibility of being subjected to conditions that could result in a material delay in, or the abandonment of, the merger or otherwise have an adverse effect on the Company; continued availability of financing or alternatives for the financing provided in the Knauf debt commitment letter; the failure to satisfy required closing conditions; the potential impact on the USG Boral joint venture in the event the merger is not completed, including that, in connection with the execution of the merger agreement, Boral Limited delivered a default notice under the USG Boral Shareholders Agreement to commence the process to establish the fair market value of the Company’s 50% interest in USG Boral, which could lead to Boral exercising its right to purchase the Company’s 50% interest in USG Boral; the potential negative impact on USG Boral as a result of the uncertainty

around the future ownership of USG Boral; the risk that the merger may not be completed in the expected timeframe, or at all; the effect of restrictions placed on the Company and its subsidiaries’ ability to operate their businesses under the merger agreement, including the Company’s ability to pursue alternatives to the merger; the risk of disruption resulting from the merger, including the diversion of the Company’s resources and management’s attention from ongoing business operations; the effect of the pendency of the merger on the Company’s ability to retain and hire key employees; the effect of the pendency of the merger on the Company’s business relationships, results of operations, financial condition, the market price of the Company’s common stock and businesses generally; the risk of negative reactions from investors, employees, suppliers and customers; the outcome of legal proceedings that have been instituted against the Company related to the merger and any additional proceedings that may be instituted in the future; the amount of the costs, fees, expenses and charges related to the merger; and the occurrence of any event giving rise to the right of a party to terminate the merger agreement. Information describing other risks and uncertainties affecting the Company that could cause actual results to differ materially from those in forward-looking statements may be found in the Company’s filings with the SEC, including, but not limited to, the “Risk Factors” in the Company’s most recent Annual Report on Form 10-K and most recent Quarterly Report on Form 10-Q.
