Context
RSU grants are compensation awards, not open‑market purchases or sales, and do not by themselves signal a buy or sell decision by the insider. The immediate vesting portion (2,267 RSUs) resulted in an acquisition of shares on the vest date; the remaining RSUs are time‑based and subject to service through the vesting date. No cash sales, option exercises, or 10b5-1 plans are indicated in this report.
