Ownership structure and post-issue operating performance of firms conducting seasoned equity offerings in Thailand

This paper investigates the post-issue operating performance of companies that conducted seasoned equity offerings (SEO) in the Stock Exchange of Thailand (SET) during the period 1991 to 1994. It is documented that SEO firms exhibited declining operating performance after the offering. Further, there is a negative relation between inside ownership concentration and postissue operating performance decline. In support of the signaling effect, the ratio of issue proceeds to pre-issue equity also negatively relates to post-issue operating performance. Further, the negative relation between issue proceeds and operating performance decline is intensified among SEO firms with high insider ownership concentration. The finding offers evidence in support of agency conflicts and information asymmetry and suggests that the two factors are operating simultaneously.
