Testing The Merger Premiums In Publicly Traded Firms: The Case Of U.S. Commercial Banks

This study examines the short-term wealth effects of the mergers and acquisitions (M&As) transactions that were announced between 2000 and 2014 in U.S. Banking Industry. In particular, the merger premiums before and after the Global Financial Crisis (2008-2009) are examined. The results reveal that, on average, cumulative abnormal returns (CARs) to the target banks are 23.64% while CARs to the bidders are -1.24% around the announcement date over the sample period. We also find statistically significant positive CARs of 2.42% for the combined banks. The findings point out that M&As are value-creating events for the combined banks due to synergies created between bidders and targets; however, bidders may sometimes overpay to realize these gains. Our findings also reveal that M&As taking place before the Global Financial Crisis period (2000- 20007) realize lower gains for targets, bidders and combined firms compared post-Crisis period (2010-2014) possibly due to stronger banks surviving the Crisis and existence of a more prudent and reliable market environment after the passage of Dodd-Frank Act.
