Context
RSU grants are common director compensation and do not require a cash outlay by the recipient. Because these are time-vested awards (with potential acceleration on the merger Closing), they indicate compensation alignment with future service and corporate events rather than an open-market purchase or sale. The filing does not disclose total post-transaction beneficial ownership, and no sale or purchase (open-market) occurred in this report.
