Abstract
This paper provides empirical evidence of the impact of the voluntary disclosure of management earnings forecasts in IPO prospectuses and of the credibility of these forecasts, as perceived by investors at the time of the IPO. We measure forecast credibility ex ante with two approaches: (i) a vector of determinants of credibility that are observable by market participants at the time of the issue and (ii) the predicted value of the forecast error based on some of these determinants. Controlling for the firm's decision on whether or not to issue a forecast, we find that the issue of a forecast reduces underpricing. We find that the quality of the firm's governance and of the auditor and underwriter associated with the issue seems to act as a substitute to the disclosure of an earnings forecast in the prospectus, so that they significantly decrease the level of underpricing only for non‐forecasters. However, despite our various approaches to measure ex ante credibility, we find no association between the pricing of the issue and perceived forecast credibility at the time of the IPO.
