Administrative tax withholding; no change to insider intent.

The reported Code F transaction reflects shares withheld (965) to satisfy taxes from the vesting of a prior equity grant (1,890 shares). Such withholding is a common, non-discretionary mechanism and does not indicate an open-market sale.

Footnotes state this includes 29,376 RSUs vesting starting August 5, 2026 and 5,670 restricted shares vesting starting November 6, 2026, contingent on continued employment. Any future share delivery depends on those vesting conditions.
