Dr Shan Ji and colleagues show that the presence of end-of-day (EOD) target price manipulation prior to M&As increases the probability of an M&A deal withdrawal, and decreases the premium paid. Having looked at M&As from over 45 countries from 2003 to 2014, they find that more detailed exchange trading rules lower the probability of withdrawal, mitigate the negative impact of EOD manipulation on withdrawal, and raise premiums paid. Finally, while there are fewer cases of acquirer price manipulations prior to M&As, the data indicate that positive acquirer price manipulation in share M&As increases the probability of deal withdrawal.
