Context

• As a reported 10% owner, Riggs is a substantial shareholder; this is not necessarily the same as an employee/executive insider trade.
• The purchase was executed in a firm commitment public offering (not an open-market trade), meaning the shares were acquired at the offering price rather than via market purchases.
