Context

• These are standard compensation grants (RSUs and options) that represent future economic interest if/when they vest; RSUs convert into one share per unit upon vesting.
• The small share disposition was for statutory tax withholding and should not be read as a directional bet by the insider.
• No open‑market purchases or large outright sales were reported in this filing.
