This Amendment No. 5 to Schedule 13D (this “Amendment No. 5”) is being filed with respect to the common shares, par value $0.01 per share (“Common Stock”), of Arch Coal, Inc. (the “Issuer”), to amend the Schedule 13D filed on October 17, 2016 (together with Amendment No.1 to Schedule 13D filed on November 22, 2016, Amendment No. 2 to Schedule 13D filed on September 15, 2017, Amendment No. 3 to Schedule 13D filed on December 12, 2017 and Amendment No. 4 to Schedule 13D filed on December 3, 2018 (which was inadvertently filed as Schedule 13D), the “Schedule 13D”). Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to them in the Schedule 13D.

Item 4.
Purpose of the Transaction.

Item 4 of the Schedule 13D is hereby amended to include the following:

On December 14, 2018, in an effort to assist the Issuer in its share buyback program by making shares of Common Stock available for purchase in addition to the shares available in the open market, MAC proposed to the Issuer that the Issuer repurchase 558,000 shares of Common Stock from the Funds at a price of $87.00 per share.  The Issuer declined MAC’s proposal, indicating that it has been satisfied with the number of shares that it has been able to purchase through open market transactions.
