According to the filing footnote, the shares were sold to satisfy tax withholding obligations related to the vesting of previously granted restricted stock units (RSUs) and do not represent a discretionary sale.

Key Details

• Transaction date and price: 2026-05-15 at $2.67 per share.
• Shares sold: 543 — gross proceeds ~$1,450.
• Reason: Footnote F1 states sale was to satisfy tax withholding on vested RSUs (not a discretionary sale).

Context
This was a withholding sale tied to RSU vesting — a routine administrative transaction to cover taxes, which typically does not signal the insider’s view on the company. For retail investors, purchases or discretionary sales by insiders tend to carry more interpretive weight than tax-withholding disposals.
