FORWARD-LOOKING STATEMENTS: Certain statements in this press release are forward-looking and reflect current analysis of existing information. Caution must be exercised in relying on forward-looking statements. Due to known and unknown risks, the Company’s actual results may differ materially from its expectations or projections. Factors potentially contributing to such differences include, among others: market demand for coal, electricity and steel which could adversely affect the Company’s operating results and cash flows; future economic or capital market conditions; deregulation of the electric utility industry; competition in coal markets; inherent risks of coal mining beyond the Company’s control, including weather and geologic conditions; the Company’s ability to expand mining capacity; the Company’s future production capabilities; failure to receive anticipated new contracts; customer cancellations of, or breaches to, existing contracts; customer delays or defaults in making payments; the Company’s ability to manage production costs; fluctuations in the demand for, price and availability of, coal due to labor and transportation costs and disruptions, governmental policies and regulatory actions, legal and administrative proceedings, settlements, investigations and claims, foreign currency changes and other factors; and greater than expected environmental and safety regulation, costs and liabilities. The forward-looking statements are also based on various operating assumptions regarding, among other things, overhead costs and employment levels that may not be realized. While most risks affect only future costs or revenues anticipated by the Company, some risks might relate to accruals that have already been reflected in earnings. The Company’s failure to receive payments of accrued amounts could result in a charge against future earnings.

Additional information concerning these and other factors can be found in press releases as well as Massey’s public filings with the Securities and Exchange Commission, including the Company’s Form 10-K for the year ended December 31, 2004, which

was filed on March 16, 2005, and subsequently filed interim reports.
