The following factors are among those that may cause actual results to differ materially from Walter Energy’s forward-looking statements: unfavorable economic, financial and business conditions; a substantial or extended decline in pricing, demand, and other factors beyond Walter Energy’s control; failure of Walter Energy’s customers to honor or renew contracts; Walter Energy’s ability to collect payments from its customers; inherent risks in coal mining that are beyond Walter Energy’s control; title defects preventing us from (or resulting in additional costs for) mining Walter Energy’s mineral interests; concentration of Walter Energy’s mining operations in a limited number of areas; a significant reduction of or loss of purchases by Walter Energy’s largest customers; unavailability or uneconomical transportation for Walter Energy’s coal; significant competition and foreign currency fluctuation; significant cost increases and fluctuations, and delay in the delivery of raw materials, mining equipment and purchased components; work stoppages, labor shortages and other labor relations matters; Walter Energy’s ability to hire and retain a skilled labor force; risks associated with Walter Energy’s reclamation and mine closure obligations; inaccuracies in Walter Energy’s estimates of coal reserves; Walter Energy’s ability to develop or acquire coal reserves in an economically feasible manner; challenges to Walter Energy’s licenses, permits and other authorizations; failure to meet project development and expansion targets; risks associated with operating in foreign jurisdictions; risks associated with environmental, health and safety laws and regulations; risks associated with federal, state and provincial regulatory agencies’ authority to order temporary or permanent closure of Walter Energy’s mines; increased focus by regulatory authorities on the effects of surface coal mining on the environment; risks related to climate change concerns; risks related to Walter Energy’s operations’ impact on the environment; risks related to Walter Energy’s indebtedness; Walter Energy’s ability to generate cash for its financial obligations, to refinance its indebtedness or to obtain additional financing; Walter Energy’s ability to incur additional indebtedness; restrictions in Walter Energy’s existing and future debt agreements; events beyond Walter Energy’s control may result in an event of default under one or more of its debt instruments; downgrades in Walter Energy’s credit ratings; failure to obtain or renew surety bonds on acceptable terms could affect Walter Energy’s ability to secure reclamation and coal lease obligations; costs associated with Walter Energy’s pension and benefits, including post-retirement benefits; costs associated with Walter Energy’s workers’ compensation and certain medical and disability benefits; adverse rulings in current or future litigation; Walter Energy’s ability to attract and retain key personnel; Walter Energy’s ability to identify or integrate suitable acquisition candidates to promote growth; volatility in the price of Walter Energy’s common stock; Walter Energy’s ability to pay regular dividends to stockholders; Walter Energy’s exposure to indemnification obligations; risks associated with terrorist attacks and threats and escalation of military activity in response to such attacks; risks associated with cyber-attacks or other security breaches; and other risks and uncertainties including those described in Walter Energy’s filings with the SEC. Forward-looking statements made by Walter Energy 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 Walter Energy’s most recently filed Annual Report on Form 10-K and subsequent filings with the SEC, which are available on Walter Energy’s 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 Walter Energy to predict these events or how they may affect it or its anticipated results. Walter Energy has no duty to, and does 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.

Walter Energy, Inc. and Subsidiaries Reconciliation of Non-GAAP Financial Measures (Unaudited) Note: EBITDA from continuing operations is defined as earnings excluding discontinued operations before interest expense, interest income, income taxes, and depreciation and depletion expense. EBITDA from continuing operations 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 from continuing operations is a useful measure as some investors and analysts use EBITDA from continuing operations 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 may not be comparable to similarly titled measures used by other companies. EBITDA is defined as net income (loss) before interest expense, interest income, income taxes, and depreciation and depletion expense. EBITDA is a financial measure which is not 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 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 net restructuring charges, asset impairments, loss on investment, other items including proxy contest expenses and foreign currency adjustments and gain on early extinguishment of debt. 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 GAAP. 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 loss excluding income from discontinued operations, net restructuring charges, asset impairments, loss on investment, other items including proxy contest expenses and foreign currency adjustments, gain on early extinguishment of debt, and discrete income tax charges from valuation allowance adjustments, net of tax. Adjusted net income (loss) is not a measure of financial performance in accordance with GAAP, 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. 24 Reconciliation of EBITDA from Continuing Operations, EBITDA and Adjusted EBITDA to Amounts Reported Under U.S. GAAP: For the Three Months Ended March 31, For the Years Ended December 31, ($ in Thousands) 2014 2013 2013 2012 Loss from continuing operations (92,178) (49,444) (359,003) (1,065,555) Interest expense 79,396 52,618 233,854 139,356 Interest income (75) (650) (1,103) (804) Income tax benefit (35,961) (66,039) (41,838) (99,204) Depreciation and depletion expense 76,424 81,190 311,514 316,232 Earnings from continuing operations before interest, income taxes, and depreciation and depletion (EBITDA from continuing operations) (1) 27,606 17,675 143,424 (709,975) Pretax income from discontinued operations - - - 8,282 Earnings before interest, income taxes, and depreciation and depletion (EBITDA) (2) 27,606 17,675 143,424 (701,693) Restructuring and asset impairment - 7,440 2,883 1,113,479 Loss on investment - - 1,336 - Other items, including proxy contest expenses and foreign currency adjustments (3,076) 6,838 5,866 - Gain on early extinguishment of debt - - (4,293) - Loss on interest rate swap hedge ineffectiveness 1,701 - - - Adjusted EBITDA (3) 26,231 31,953 149,216 411,786 Reconciliation of Adjusted Net Income (Loss) to Amounts Reported Under U.S. GAAP: Net loss (92,178) (49,444) (359,003) (1,060,375) Income from discontinued operations, net of tax - - - (5,180) Restructuring and asset impairment, net of tax - 4,851 2,063 1,096,277 Loss on investment, net of tax - - 827 - Other items, including proxy contest expenses and foreign currency adjustments, net of tax (1,999) 4,449 3,369 - Gain on early extinguishment of debt, net of tax - - (2,657) - Discrete tax charge from valuation allowance adjustment - - 144,619 19,189 Adjusted net income (loss) (4) (94,177) (40,144) (210,782) 49,911 Weighted average number of diluted shares outstanding 62,601,240 62,598,990 62,563,870 62,536,239 Adjusted diluted income (loss) per share: (1.50) (0.64) (3.37) 0.80
