Qualcomm also stated that if the merger would take place, Broadcom would lose one of their customers.
Why would they care if the shareholders no longer hold Qualcomm shares any more? The deal is $60 cash and $22 in share equivilent. If they don't want to hold Broadcom for any reason, they can sell their shares and walk away.
I plan to sell my Broadcom shares once the deal is closed. I bought QCCOM strictly for price appreciation and a quick gain when Q and Apple started their feuding.
