Key Details
- Transaction date: 2026-02-12; price: $12.03 per share; total proceeds: ~$5,004.

- Shares owned after transaction: Not specified in the provided filing.

Context
The footnote indicates this was a tax-withholding sale tied to RSU vesting, a common administrative transaction that typically reflects tax needs rather than a directional bet on the company. Sales of this size by executives for tax withholding are routine and should be interpreted differently than discretionary large-scale insider selling.
