More than one in five listed firms in China initiate dividend payments during the year right before their initial public offerings (IPOs). This tendency, which seems to contradict the purpose of raising capital, constitutes the pre-IPO dividend puzzle. This paper examines this puzzle using manually collected Chinese data from 2006 to 2019. We find that firms initiating pre-IPO dividends tend to have lower IPO underpricing than non-initiating firms. We also find that the effect of pre-IPO dividend initiation on IPO underpricing is more pronounced for firms with stronger pre-IPO growth and profitability. Additional analyses indicate that initiating firms have better pre- and post-IPO operating performance and post-IPO stock performance. Moreover, initiating firms pay more dividends and have significantly higher investor attention after the IPOs. Collectively, the pre-IPO dividend initiation is not a short-term strategic behavior of low-quality firms but is intended to send positive signals and improve investors’ stock valuation.
