Stockholder returns and international acquisitions of financial firms: An emphasis on banking

The wealth effects for shareholders of American financial firms involved in foreign acquisitions and also the wealth effects for shareholders of U.S. target firms acquired by foreign concerns are the topics of this study. The findings indicate that stockholders of U.S. bidding financial firms (and its subset of banks) earn neither abnormal gains nor suffer abnormal losses upon the announcement of an acquisition or regulatory approval. On the other hand, stockholders of U.S. target financial firms (and its subset of banks) earn significant abnormal profits at both the announcement of the proposed acquisition and the announcement of regulatory approval of the acquisition. The wealth effects for these two samples are also compared to samples in which both parties to the acquisition are U.S. firms. The research suggests that there is no significant difference in the size of the announcement gains or losses for either stockholders of the target or bidding firms based on whether the acquisition is foreign or domestic. These findings conflict with prior research which indicates that, for firms in general, stockholders of U.S. targets earn significantly greater wealth benefits when they are acquired by foreign firms than by domestic firms. Overall, these results are consistent with a competitive market for acquisitions of financial firms in which buyers do not earn or lose at the announcement of an acquisition, and in which abnormal gains are received only by the sellers.
