Both a firm's market-timing opportunities and its corporate lifecycle stage exert statistically and economically significant influences on the probability that it conducts a seasoned equity offering (SEO), with the lifecycle effect empirically stronger. Neither effect adequately explains SEO decisions because a near-majority of issuers are not growth firms and the vast majority of firms with high M/B ratios and high recent and poor future stock returns fail to issue stock. Since without the offer proceeds 62.6% of issuers would run out of cash (81.1% would have subnormal cash balances) the year after the SEO, a near-term cash need is the primary SEO motive, with market-timing opportunities and lifecycle stage exerting only ancillary influences.
