Context

These transactions reflect an institutional holder converting preferred into publicly traded Class A common in connection with the company’s IPO and then disposing of those shares. As a 10% institutional owner (not an executive), this is a structural liquidity event related to conversion and disposition of previously held preferred shares rather than a routine insider buy/sell decision by company management.
