Arch Coal Commences Public Offering of Common Stock

     ST. LOUIS (July 27, 2009) — Arch Coal, Inc. (NYSE:ACI) today announced that it has commenced an offering of 17,000,000 shares of its common stock pursuant to an automatic shelf registration statement on Form S-3 filed previously with the Securities and Exchange Commission (SEC). The company intends to grant the underwriters of the common stock offering an option for 30 days to purchase up to 2,550,000 additional shares of common stock to cover over-allotments, if any.

     The company plans to use the net proceeds of the offering to finance a portion of the $761.0 million purchase price for the previously announced acquisition of the Jacobs Ranch mining complex in Wyoming. The acquisition is expected to close in the third quarter of 2009. If the acquisition is not completed, the company intends to use the net proceeds from this offering for general corporate purposes, which may include the financing of future acquisitions, including lease-by-applications, or strategic combinations, capital expenditures, additions to working capital, repurchases, repayment or refinancing of debt or stock repurchases.

     This press release shall not constitute an offer to sell or a solicitation of an offer to buy any securities.

     BofA Merrill Lynch, Morgan Stanley & Co. Incorporated, Citigroup Global Markets Inc. and J.P. Morgan Securities Inc. are the joint book-runners for the common stock offering.

     The company has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates.

     Forward-Looking Statements: This press release contains “forward-looking statements” — that is, statements related to future, not past, events. In this context, forward-looking statements often address our expected future business and financial performance, and often contain words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” or “will.” Forward-looking statements by their nature address matters that are, to different degrees, uncertain. For us, particular uncertainties arise from changes in the demand for our coal by the domestic electric generation industry; from legislation and regulations relating to the Clean Air Act and other environmental initiatives; from operational, geological, permit, labor and weather-related factors; from fluctuations in the amount of cash we generate from operations; from future integration of acquired businesses; and from numerous other matters of national, regional and global scale, including those of a political, economic, business, competitive or regulatory nature. These uncertainties may cause our actual future results to be materially different than those expressed in our forward-looking statements. We do not undertake to update our forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required by law. For a description of some of the risks and uncertainties that may affect our future results, you should see the risk factors contained in the prospectus and prospectus supplement related to the offering or otherwise described from time to time in the reports we file with the Securities and Exchange Commission.
