Forward-Looking & Non-GAAP Statements 1 Except for historical information contained herein, the statements in this document are forward-looking and made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and may involve a number of risks and uncertainties. Forward-looking statements are based on information available to management at the time, and they involve judgments and estimates. Forward-looking statements include expressions such as "believe," "anticipate," "expect," "estimate," "intend," "may," "plan," "predict," "will," and similar terms and expressions. These forward-looking statements are made based on expectations and beliefs concerning future events affecting us and are subject to various risks, uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control, which could cause our actual results to differ materially from those matters expressed in or implied by these forward-looking statements. The following factors are among those that may cause actual results to differ materially from our forward-looking statements: unfavorable economic, financial and business conditions; the global economic crisis; market conditions beyond our control; prolonged decline in the price of coal; decline in global coal or steel demand; prolonged or dramatic shortages or difficulties in coal production; our customer's refusal to honor or renew contracts; our ability to collect payments from our customers; inherent risks in coal mining such as weather patterns and conditions affecting production, geological conditions, equipment failure and other operational risks associated with mining; title defects preventing us from (or resulting in additional costs for) mining our mineral interests; concentration of our mining operations in limited number of areas; a significant reduction of, or loss of purchases by, our largest customers; unavailability of cost-effective transportation for our coal; availability, performance and costs of railroad, barge, truck and other transportation; disruptions or delays at the port facilities we use; risks associated with our reclamation and mine closure obligations, including failure to obtain or renew surety bonds; significant increase in competitive pressures and foreign currency fluctuations; significant cost increases and delays in the delivery of raw materials, mining equipment and purchased components; availability of adequate skilled employees and other labor relations matters; inaccuracies in our estimates of our coal reserves; estimates concerning economically recoverable coal reserves; greater than anticipated costs incurred for compliance with environmental liabilities or limitations on our abilities to produce or sell coal; our ability to attract and retain key personnel; future regulations that increase our costs or limit our ability to produce coal; new laws and regulations to reduce greenhouse gas emissions that impact the demand for our coal reserves; adverse rulings in current or future litigation; inability to access needed capital; events beyond our control that may result in an event of default under one or more of our debt instruments; availability of licenses, permits, and other authorizations that may be subject to challenges; risks associated with our reclamation and mine closure obligations; failure to meet project development and expansion targets; risks associated with operating in foreign jurisdictions; risks related to our indebtedness and our ability to generate cash for our financial obligations; downgrade in our credit rating; our ability to identify suitable acquisition candidates to promote growth; our ability to integrate acquisitions successfully; our exposure to indemnification obligations; volatility in the price of our common stock; our ability to pay regular dividends to stockholders; costs related to our post-retirement benefit obligations and workers' compensation obligations; our exposure to litigation; and other risks and uncertainties including those described in our filings with the SEC. Forward-looking statements made by us in this document, or elsewhere, speak only as of the date on which the statements were made. You are advised to read the risk factors in our most recently filed Annual Report on Form 10-K and subsequent filings with the SEC, which are available on our website at www.walterenergy.com and on the SEC's website at www.sec.gov. New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us or our anticipated results. We have no duty to, and do not intend to, update or revise the forward-looking statements in this document, except as may be required by law. In light of these risks and uncertainties, readers should keep in mind that any forward-looking statement made in this document may not occur. All data presented herein is as of the date of this document unless otherwise noted. We use a number of different financial measures in assessing the overall performance of our business, including measures calculated in accordance with United States generally accepted accounting principles (“GAAP”) and non-GAAP numbers. EBITDA from Continuing Operations, EBITDA, Adjusted EBITDA and Adjusted Net Income (Loss) are financial measures that are calculated in conformity with GAAP and should be considered supplemental to, and not as a substitute or superior to, financial measures calculated in conformity with GAAP. We believe that EBITDA from Continuing Operations, EBITDA, Adjusted EBITDA and Adjusted Net Income (Loss) are useful measures as some investors and analysts use EBITDA from Continuing Operations, EBITDA, Adjusted EBITDA and Adjusted Net Income (Loss) to compare us against other companies and to help analyze our ability to satisfy principal and interest obligations and capital expenditure needs. EBITDA from Continuing Operations, EBITDA, Adjusted EBITDA and Adjusted Net Income (Loss) may not be comparable to similarly titled measures used by other companies. A reconciliation of these non-GAAP measures is included in the Appendix hereto.

EBITDA is a financial measure which is not calculated in conformity with U.S. Generally Accepted Accounting Principles (GAAP) and should be considered supplemental to, and not as a substitute or superior to financial measures calculated in conformity with GAAP. We believe that EBITDA is a useful measure as some investors and analysts use EBITDA to compare us against other companies and to help analyze our ability to satisfy principal and interest obligations and capital expenditure needs. EBITDA may not be comparable to similarly titled measures used by other companies. Adjusted EBITDA is defined as EBITDA further adjusted to exclude restructuring charges (benefits), asset impairment, proxy contest expenses and other miscellaneous items, gain on early extinguishment of debt, and loss on ineffective portion of derivative instruments. Adjusted EBITDA is not a measure of financial performance in accordance with GAAP, and we believe items excluded from Adjusted EBITDA are significant to a reader in understanding and assessing our financial condition. Therefore, Adjusted EBITDA should not be considered in isolation, nor as an alternative to net income, income from operations, cash flows from operations or as a measure of our profitability, liquidity or performance under generally accepted accounting principles. We believe that Adjusted EBITDA presents a useful measure of our ability to incur and service debt based on ongoing operations. Furthermore, analogous measures are used by industry analysts to evaluate our operating performance. Investors should be aware that our presentation of Adjusted EBITDA may not be comparable to similarly titled measures used by other companies. Adjusted net income (loss) is defined as net income (loss) excluding restructuring charges (benefits) net of tax, asset impairment net of tax, proxy contest expenses and other miscellaneous items net of tax, gain on early extinguishment of debt net of tax, and loss on ineffective portion of derivative instruments net of tax. Adjusted net income (loss) is not a measure of financial performance in accordance with generally accepted accounting principles, and we believe items excluded from Adjusted net income (loss) are significant to a reader in understanding and assessing our results of operations. Therefore, Adjusted net income (loss) should not be considered in isolation, nor as an alternative to net income (loss) under generally accepted accounting principles. 31 Source: Company Filings
