Forward-Looking Statements and Other Disclaimers<\/span><\/b><\/p>\nThis press release may contain forward-looking statements, including, without limitation, statements about future costs, production, debt reduction, shareholder value, and the company’s outlook for 2026, including its expectations regarding sales volumes, revenue, Adjusted EBITDA, depreciation, depletion, and amortization, interest expense, tax rates, and capital expenditures. Forward-looking statements are those that predict or describe future events or trends and that do not relate solely to historical matters. The company uses words such as \u201cmay,\u201d \u201cwould,\u201d \u201ccould,\u201d \u201cshould,\u201d \u201cwill,\u201d \u201clikely,\u201d \u201cexpect,\u201d \u201canticipate,\u201d \u201cbelieve,\u201d \u201cintend,\u201d \u201cplan,\u201d \u201cforecast,\u201d \u201coutlook,\u201d \u201cproject,\u201d \u201cestimate\u201d and similar expressions suggesting future outcomes or events to identify forward-looking statements or forward-looking information. These statements are based on the company\u2019s current expectations and involve risks and uncertainties that could cause the company\u2019s actual results to differ materially. The differences could be caused by a number of factors, including without limitation (i) weather conditions, (ii) inflation, the cost and availability of transportation for the distribution of the company\u2019s products and foreign exchange rates, (iii) pressure on prices and impact from competitive products, and (iv) any inability by the company to successfully implement its strategic priorities or its cost-saving or enterprise optimization initiatives. For further information on these and other risks and uncertainties that may affect the company\u2019s business, see the \u201cRisk Factors\u201d and \u201cManagement\u2019s Discussion and Analysis of Financial Condition and Results of Operations\u201d sections of the company\u2019s Annual Report on Form 10-K for the period ended September 30, 2025, and its Quarterly Reports on Form 10-Q for the quarters ended December 31, 2025, March 31, 2026 and June 30, 2026, filed or to be filed with the SEC, as well as the company’s other SEC filings. The company undertakes no obligation to update any forward-looking statements made in this press release to reflect future events or developments, except as required by law. Because it is not possible to predict or identify all such factors, this list cannot be considered a complete set of all potential risks or uncertainties.<\/i><\/p>\n
Non-GAAP Measures<\/b><\/p>\n
In addition to using U.S. generally accepted accounting principles (\u201cGAAP\u201d) financial measures, management uses a variety of non-GAAP financial measures described below to evaluate the company\u2019s and its operating segments\u2019 performance. While the consolidated financial statements provide an understanding of the company\u2019s overall results of operations, financial condition and cash flows, management analyzes components of the consolidated financial statements to identify certain trends and evaluate specific performance areas.<\/i><\/p>\n
Management uses EBITDA, EBITDA adjusted for items which management believes are not indicative of the company\u2019s ongoing operating performance (\u201cAdjusted EBITDA\u201d) and EBITDA margin to evaluate the operating performance of the company\u2019s core business operations because its resource allocation, financing methods and cost of capital, and income tax positions are managed at a corporate level, apart from the activities of the operating segments, and the operating facilities are located in different taxing jurisdictions, which can cause considerable variation in net income. Management also uses adjusted operating income, adjusted operating margin, adjusted net (loss) income, and adjusted net (loss) income per diluted share, which eliminate the impact of certain items that management does not consider indicative of underlying operating performance. The presentation of these measures should not be construed as an inference that future results will be unaffected by unusual or non-recurring items. Management believes these non-GAAP financial measures provide management and investors with additional information that is helpful when evaluating underlying performance. EBITDA and Adjusted EBITDA exclude interest expense, income taxes and depreciation, depletion and amortization, each of which is an essential element of the company\u2019s cost structure and cannot be eliminated. In addition, Adjusted EBITDA and Adjusted EBITDA margin exclude certain cash and non-cash items, including stock-based compensation, impairment charges and certain restructuring charges. Consequently, any measure that excludes these elements has material limitations. The non-GAAP financial measures used by management should not be considered in isolation or as a substitute for net (loss) income, operating income, cash flows or other financial data prepared in accordance with GAAP or as a measure of overall profitability or liquidity. These measures are not necessarily comparable to similarly titled measures of other companies due to potential inconsistencies in the method of calculation. The calculation of non-GAAP financial measures as used by management is set forth in the following tables. All margin numbers are defined as the relevant measure divided by sales. The company does not provide a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable financial measures calculated and reported in accordance with GAAP, as the company is unable to estimate significant non-recurring, unusual items and\/or distinct non-core initiatives without unreasonable effort. The amounts and timing of these items are uncertain and could be material to the company\u2019s results.<\/i><\/p>\n
Adjusted operating income, adjusted operating margin, adjusted net (loss) income, adjusted net (loss) income per diluted share, net debt and net leverage ratio are presented as supplemental measures of the company\u2019s performance. Management believes these measures provide management and investors with additional information that is helpful when evaluating underlying performance and comparing results on a year-over-year normalized basis. These measures eliminate the impact of certain items that management does not consider indicative of underlying operating performance. These adjustments are itemized below. Adjusted net (loss) income per diluted share is adjusted net (loss) income divided by weighted average diluted shares outstanding. Net debt is calculated as current and long-term debt minus cash and cash equivalents used to evaluate our financial position. Management defines net leverage ratio as net debt divided by Adjusted EBITDA for the previous twelve-month period (“last twelve months,” or “LTM”). You are encouraged to evaluate the adjustments itemized above and the reasons management considers them appropriate for supplemental analysis. In evaluating these measures you should be aware that in the future the company may incur expenses that are the same as or similar to some of the adjustments presented below.<\/i><\/p>\n\n\n| \n Special Items Impacting the Three Months Ended June 30, 2025<\/b><\/p>\n \n(unaudited, in millions, except per share data)<\/p>\n<\/td>\n<\/tr>\n |
