Acquisitions and the Information Environment of Firms

This paper investigates how acquisitions affect analyst following of firms. Analyst following increases as a result of a merger. However, all of that increase can be attributed to the changes in firm-specific characteristics resulting from the merger. Changes in analyst following around mergers are positively related to changes in firm size, expenditures on R&D, and the ratio of book to the market value of equity. Finally, the relatedness of merger appears to be an important determinant of analyst following of firms engaged in acquisitions.
