"reverted to the reporting person only upon the transfer agent recording the returned shares"

A transfer agent is a financial service that keeps the official record of who owns a company's shares, handles the buying and selling of those shares on paper or electronically, and issues or cancels stock certificates. Think of it as the company’s records keeper and mailroom combined—investors rely on it to make sure dividends, shareholder mailings, ownership changes, and proxy voting are processed accurately and securely, which protects ownership rights and helps prevent errors or fraud.
