In recent years, a number of firms and banks have decided to “go dark,” i.e., deregister with the Securities and Exchange Commission and delist from the major exchanges despite having a large number of outside shareholders. This paper seeks to answer two important questions: Why do firms choose to go dark? What are the consequences for shareholders? We find that firms with fewer valuable growth opportunities, greater insider ownership, lower institutional ownership, higher leverage, and lower market momentum are more likely to go dark. Furthermore, the cost of regulatory compliance is a driving force behind the going dark phenomenon.
