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.

Exhibit 99.1

Arch Coal Receives Continued Listing Standard Notice from NYSE;

Taking Steps to Regain Compliance with Minimum Share Price Standard

ST. LOUIS, May 22, 2015 — Arch Coal, Inc. (NYSE: ACI) announced today that it received notice on May 21, 2015 from the New York Stock Exchange (the “NYSE”) that it does not presently satisfy the NYSE’s continued listing standard requiring the average closing price of a listed company’s common stock to be at least $1.00 per share for any period of 30 consecutive trading days. As of May 15, 2015, the average closing price per share of the Company’s common stock over the preceding 30 trading-day period was $0.99.

In accordance with NYSE rules, the Company will respond to the NYSE within 10 business days of receipt of the notification with its intent to resolve the deficiency. The Company has six months to regain compliance with the NYSE continued listing requirements and will actively monitor its stock price and evaluate all available options in order to regain compliance within the prescribed timeframe.

During the six-month period the Company’s common stock will continue to be listed and traded on the NYSE, subject to compliance with other continued listing standards. The deficiency does not affect the Company’s ongoing business operations or its SEC reporting requirements.

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 described from time to time in the reports we file with the Securities and Exchange Commission.
