Alpha Natural Resources Inc. and Massey Energy Co. say Alpha's proposed takeover of Massey could be completed within seven weeks.
The companies said in a joint news release Friday that special stockholder meetings will be held on June 1. If approved, the companies expect to promptly complete the acquisition.
April 27 is the date for determining the holders of common stock who will be entitled to vote at the special meetings.
Richmond-based Massey agreed to a $7.1 billion buyout offer from Abingdon-based Alpha in January. The deal has cleared regulatory approval.
Massey has struggled since the April 5, 2010, explosion that killed 29 miners at its Upper Big Branch mine in southern West Virginia.
