Context This filing documents conversion/exercise of equity awards (derivative-to-share conversion), not an open-market purchase or sale. The paired “acquired” and “disposed” entries reflect the RSU conversion mechanics (the derivative interest is extinguished as shares are issued). No sale of the newly issued shares is reported here, and no cash was paid in connection with the conversion.
