Key Details

• Transaction date: 2026-03-11; SEC filing date: 2026-03-12 (timely).
• Price: weighted average $2.04; block trade prices ranged $1.90–$2.30 (per footnote).
• Total proceeds: approximately $1,461.
• Shares owned after the transaction: not disclosed in this filing.
• Footnote F1: Sale was a mandatory "sell to cover" to satisfy tax withholding tied to RSU vesting — not a discretionary sale by the insider.
• Footnote F2: Reported price is a weighted average from a block trade; the reporting person can provide per-price breakdown on request.

Context

• "Sell-to-cover" transactions are routine when restricted stock units vest and taxes are due; they generally reflect tax obligations rather than a judgment about the company's prospects. Purchases by insiders tend to be more informative about confidence than obligatory sales.
