ACQUISITIONS OF PRIVATE VS. PUBLIC FIRMS: PRIVATE INFORMATION, TARGET SELECTION, AND ACQUIRER RETURNS

摘要

The acquisition of privately held firms is a prevalent phenomenon that has received little attention in mergers and acquisitions research. In this study, we examine three questions: (1) What drives the acquirer's choice between public and private targets? (2) Do acquisitions of private targets elicit a more positive stock market reaction than acquisitions of public targets, which, on average, destroy value for acquirers' shareholders? (3) Do acquirers gain when their selection of a public or private target fits the theory? In this paper, we argue that the lack of information on private targets limits the breadth of the acquirer's search and increases its risk of not evaluating properly the assets of private targets. At the same time, less information on private targets creates more value-creating opportunities for exploiting private information, whereas the market of corporate control for public targets already serves as an information-processing and asset valuation mechanism for all potential bidders. Using an event study and survey data, we find that: (1) acquirers favor private targets in familiar industries and turn to public targets to enter new business domains or industries with a high level of intangible assets; (2) acquirers of private targets perform better than acquirers of public targets on merger announcement, after controlling for endogeneity bias; (3) acquirers of private firms perform better than if they had acquired a public firm, and acquirers of public firms perform better than if they had acquired a private firm. These results support the expectation that acquirer returns from their target choice (private/public) are not universal but depend on the acquirer's type of search and on the merging firms' attributes.
