The long-term performance of horizontal acquisitions

This paper examines how value is created in horizontal mergers and acquisitions. More specifically, it examines the impact of post-acquisition asset divestiture and resource redeployment on the long-term performance of horizontal acquisitions. The data come from a detailed survey of acquiring firm managers and cover 253 horizontal mergers and acquisitions that were initiated by European and U.S. firms in manufacturing industries for the period 1988-1992. This study incorporates insights from the cost efficiency and resource-based theories to propose a model of the effects of asset divestiture and resource redeployment on long-term acquisition performance. Overall, our results show that both asset divestiture and resource redeployment cart contribute to acquisition performance, with, however, a significant risk of damaging acquisition performance when the divested assets and redeployed resources are those of the target.
