"On June 16, 2017, WFM agreed to be acquired by (AMZN-US, Buy rate) for a total value of $13.58 billion or $42.00 a share in cash, which represents a 20% premium to the share price prior to the announcement," Feinseth noted. "Due to the friendly nature of the transaction, and the price at about our fair value calculation, we see no other bids emerging and the transaction is scheduled to close by the end of this year."
