Abstract Text This thesis provides empirical evidence on operating performance in U.S. domestic mergers in manufacturing industries by comparing pre-merger to post-merger cost of goods sold (COGS), as well as by computing abnormal announcement stock returns. For a sample of 153 acquisitions, no significant difference in pre- and post-merger performance is found. However, target and particularly acquiring firms seem to significantly outperform industry median firms in the pre-merger period. Whereas for the stock returns, a weighted portfolio of acquirer and target shareholders’ abnormal returns is significant, the influence of operating performance on returns is only significant for target shareholders.
