Bidder’s Gain in Public M&A Transactions: Does Size Matter?

  •  Kenneth Högholm    


In this paper we investigate the short term abnormal return to the bidding firm’s shareholders in takeovers made by a Finnish company during the time period from January 2000 to December 2013. Specifically, we study takeover transactions involving publicly traded target companies, and are particularly interested in the relationship between the abnormal return to bidder’s shareholders and the size of the transaction. Specific features of the market for corporate acquisitions in Finland are that almost all transactions are friendly acquisitions and usually aim for 100% of the target company. We estimate the abnormal return around 51 individual takeover announcements and investigate determinants of the abnormal returns. Our results show that the takeover announcement on average yields a positive, but insignificant abnormal return to the bidding firm’s shareholders. The announcement effect on the announcement day is 0.63%, while the cumulative average abnormal return for an eleven day event window is 1.39%. Both pre-event and post-event abnormal returns are statistically insignificant, although there is sign of a price run-up during the last week prior to the announcement. We document a significant negative relationship between the bidder’s abnormal return on the announcement day and the size of the deal, but a positive relationship between the announcement effect and the relative size of the deal. We also document a weak negative relationship between the abnormal returns and the relative size of the target to the bidder. Among the other takeover characteristics we do not find any statistically significant relationship to the announcement effect.
