Social trust distance in mergers and acquisitions

We study the role of regional cultural differences in M&A transactions in the U.S. A larger social trust distance between two companies reduces the likelihood of them combining via an M&A transaction and results in lower completion rates and longer completion times, indicating higher complexity in deal ex-ecution. However, a larger social trust distance is also associated with higher gains from mergers, as measured by acquirer and combined announcement returns and medium-term buy-and-hold abnormal returns. This suggests that for these announced deals, the synergy potential is high enough to offset the costs induced by the large cultural distance.(c) 2023 The Author(s). Published by Elsevier B.V.
