This study compares the SEO activity of young dual- and single-class firms. Because they hold stock with superior voting rights, dual-class insiders weigh different costs and benefits when issuing equity. Most importantly, the marginal dilution of voting power resulting from an SEO is lower in dual-class firms. This suggests that dual-class firms may issue equity more frequently, or under a different set of circumstances than singles. We find dual-class firms require a significantly lower post-IPO run-up in stock price to trigger an SEO issuance than do single-class firms. Moreover, returns prior to SEO announcements are smaller for dual-class firms, suggesting that the threshold at which SEO benefits outweigh costs is lower for these firms. We interpret this finding as evidence that single-class issuers signal more severe overvaluation when they sell their own shares in an SEO compared to dual-class insiders. Overall, SEO announcement returns are similar for both firm types.
