Background

On June 1, 2011, pursuant to the Agreement and Plan of Merger dated as of January 28, 2011 (the “Merger Agreement”), among Massey Energy Company, a Delaware corporation (“Massey”), Alpha Natural Resources, Inc., a Delaware corporation (“Alpha”), and Mountain Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Alpha (“Merger Sub”), Merger Sub was merged with and into Massey, with Massey, which was renamed Alpha Appalachia Holdings, Inc., continuing as the surviving corporation and as a wholly owned subsidiary of Alpha (the “Merger”).

Item 2.01 Completion of Acquisition or Disposition of Assets.

Immediately after the effective time of the Merger (the “Effective Time”), Massey stockholders owned approximately 46 percent and stockholders of Alpha prior to the Merger owned approximately 54 percent of Alpha on a fully diluted basis.

At the Effective Time, each issued and outstanding share of common stock, par value $0.625, of Massey (other than any shares owned by (i) Alpha, Massey or any of their respective subsidiaries (which will be canceled) or (ii) any stockholders who properly exercised and perfected appraisal rights under Delaware law, if any) was converted into the right to receive $10.00 in cash and 1.025 shares of common stock, par value $0.01, of Alpha (the “Merger Consideration”). No fractional shares of Alpha common stock will be issued in the Merger, and Massey’s former stockholders will receive cash in lieu of fractional shares, if any, of Alpha common stock. The sources of funds used in connection with the Merger include cash and cash equivalents on hand, net proceeds from the Term Loan A facility under Alpha’s Third Amended and Restated Credit Agreement and net proceeds from the offering of Alpha’s newly issued 6% Senior Notes due 2019 and 6.25% Senior Notes due 2021.

This description of the Merger does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached to this Current Report on Form 8-K as Exhibit 2.1 and incorporated herein by reference, and to the description of the Merger Agreement contained in the Current Report on Form 8-K filed by Massey on January 31, 2011.

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

In connection with the Merger, Massey notified the New York Stock Exchange (the “NYSE”) that each issued and outstanding share of Massey common stock was canceled and converted into the right to receive the Merger Consideration and requested that the NYSE file a notification of removal from listing on Form 25 with the Securities and Exchange Commission with respect to Massey common stock. Massey common stock was delisted and removed from trading on the NYSE effective at the close of market trading on June 1, 2011. Additionally, Massey intends to file with the Securities and Exchange Commission a certification on Form 15 under the Securities Exchange Act of 1934 (the “Exchange Act”) requesting that the Massey common stock be deregistered and that Massey’s reporting obligations under Sections 13 and 15(d) of the Exchange Act be suspended.
