Context

• This was a derivative/option modification (extension of expiration), not an exercise or open-market buy/sell. No shares were reported as issued or sold and no proceeds were involved in this entry.
• As a 10% owner, Qu is a significant insider; modifications to option terms can affect timing or economics of potential future exercises but do not, by themselves, indicate a purchase or sale of underlying stock.
