This study examines the role of the Securities and Exchange Commission (SEC) in mergers and acquisitions (M&As) involving publicly traded target firms. We find that M&As receiving comment letters have an increased likelihood of deal completion and positive deal price revision, consistent with the SEC review process reducing information asymmetry, albeit at the cost of delaying the M&A process. We then provide evidence that the comment letter process generates new information via firms’ disclosure amendments in response to comment letters. We address endogeneity concerns using multiple approaches. Our findings that the SEC review process reduces information asymmetry in M&As provide new insight into the real economic consequences of disclosure regulation.
