4 terms

Section 16 reporting requirements regulatory

"being filed voluntarily by the reporting person, who is not subject to Section 16 reporting requirements"

Rule 10b5-1 plan regulatory

"No Rule 10b5-1 plan is reported for the transactions in this filing"

A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.

indirect ownership financial

"Indirect ownership is reported as 53,616 shares held by spouse"

Executive Chair other

"Eric H. L. So serves as Executive Chair of CYBIN INC."

An executive chair is the board chairperson who also takes an active, hands-on role in company management, typically working closely with the CEO and senior team to shape strategy and major decisions. For investors it matters because this blend of oversight and operational power can accelerate strategic moves and provide steady leadership—like a coach who also calls plays—but it can also concentrate authority and create governance or succession risks if too much depends on one person.
