Do mega-mergers create value? the acquisition experience and mega-deal outcomes.

Hu, N. and Li, L. and Li, H. and Wang, X. (2020) 'Do mega-mergers create value? the acquisition experience and mega-deal outcomes.', Journal of empirical finance., 55 . pp. 119-142.


Existing literature shows that mega-M&A deals valued over $500mil end up destroying the shareholder value of acquirers on a significant scale. Our paper considers mega-deal as a dependent event and examines the role of acquirer’s previous acquisition experience playing in the outcome of mega-deals. We find that mega-deals conducted by firms with a high level of acquisition experience, i.e. a firm completed at least 12 transactions before, are more likely to be completed. In addition, more experienced acquirer of mega-deals generate positive abnormal stock returns for shareholders in both short-run and long-run, with a dollar value gain of $50.6 million around deal announcement. We also find that more experienced acquirers are better at managing the post-acquisition integration process and enjoy a significant improvement in operating performance.
