Corporate governance and market performance of parent firms following equity carve-out announcements

Using the Gompers, Ishii, and Metrick corporate governance index on a sample of 158 parent firms, this study demonstrates that firms with a superior governance rating have a higher short-term market reaction to carve-out announcements relative to firms with an inferior governance rating. Although the data supports previous evidence regarding negative long-term market reaction that parent firms typically experience following equity carve-outs, the results show that well-governed firms marginally outperform others. The findings also confirm that the dynamic effects related to improvements in corporate governance positively affect the long-term market outcome of parent firms; this relation is more significant in well-governed parent firms. Finally, the study shows evidence that corporate governance helps mitigate the agency problems related to the financing hypothesis, which results in better short and long-term market reactions following carve-out announcements.
