Alpha Natural Resources Inc shareholders have approved the coal company's takeover of rival Foundation Coal Holdings Inc, a company spokesman said on Friday.
Further details on the vote were not immediately available.
Alpha's largest shareholder, Duquesne Capital Management, opposed the deal and had been lobbying investors to join it in voting against the transaction.
Foundation stockholders will receive 1.084 shares of a new company, also called Alpha Natural Resources, for each of their shares. Alpha shareholders will receive one share in the new company for each of their shares.
