Though the announcement losses to acquiring-firm shareholders in the 1980s are more than offset by gains to acquired-firm shareholders, the losses of bidders exceed the gains of targets from 1998 through 2001 by $134 billion. The 1998-2001 aggregate dollar loss of acquiring-firm shareholders is so large because of a small number of acquisition announcements by firms with extremely high valuations. Without these announcements, the wealth of acquiring-firm shareholders would have increased. The large losses are consistent with the existence of negative synergies from the acquisitions, but the size of the losses in relation to the consideration paid for the acquisitions is large enough that part of the losses most likely results from investors reassessing the standalone value of the bidders. Firms that announce acquisitions with large dollar losses perform poorly afterwards. ER -
