Context

• These are compensation grants (RSUs and a derivative award) rather than purchases or sales. The reported $0.00 per share reflects that these were awarded, not bought; market value at grant is not provided in this filing. Awards like these are common for directors and reflect compensation/retention rather than an immediate trading signal.
