Drawing from complexity theory and matching theory, we propose that M&As increase data breaches and this effect is contingent on the M&A diversity (dissimilarity between the parent and target firms). Based on the 18-year panel data (2004-2021) of 5072 public firms in the United States, we find that more M&A events by a firm lead to more data breaches. More important, we reveal that the number of data breaches is amplified if the parent and target firms are dissimilar in terms of their business domains. This finding is confirmed when we conceptualize M&A diversity as size discrepancy between the parent and target firms or strategic type difference (vertical vs. horizontal M&A). Furthermore, we explore the mechanisms through which M&As influence data breaches from two additional perspectives: M&A media publicity, and target vulnerability. Our analyses demonstrate that M&As that have attracted higher media publicity suffer from more data breaches, but M&As involving a more vulnerable target firm result in fewer data breaches than those involving a less vulnerable target firm. This study not only confirms the impact of M&As on data breach recurrence but also unveils various underlying mechanisms of this impact, thus making a significant contribution to both research and practice in information systems.個(gè)人簡(jiǎn)介：Huigang Liang is FedEx Chair of Excellence in IS at Fogelman College of Business and Economics, University of Memphis.
