Item 3.01    Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On May 21, 2015, Arch Coal, Inc. (the “Company”) was notified by the New York Stock Exchange (the “NYSE”) that the average closing price of the Company’s common stock had fallen below $1.00 per share over a period of 30 consecutive trading days, which is the minimum average share price required by the NYSE under Section 802.01C of the NYSE Listed Company Manual (“Section 802.01C”).

In response, as required by Section 802.01C, the Company plans to notify the NYSE of its intent to cure the deficiency and restore its compliance with the listing standards of Section 802.01C, and it will submit a plan outlining the actions it intends to take to do so.  Under Section 802.01C, the Company has six months following receipt of the notification to regain compliance with the minimum share price requirement.

The notice has no immediate impact on the listing of the Company’s common stock, which will continue to be listed and traded on the NYSE during this period, subject to the Company’s compliance with other listing standards, under the symbol “ACI,” but with the added designation of “.bc” to indicate the Company’s “below compliance” status. In the event that the Company fails to restore its compliance with the continued listing standards of Section 802.01C, that section calls for the NYSE to commence procedures for the suspension and delisting of the Company’s common stock.

As required under Section 802.01C, the Company issued a press release on May 22, 2015, announcing that it had received a notice of noncompliance. A copy of that press release is attached hereto as Exhibit 99.1.

Item 9.01                                           Financial Statements and Exhibits.
