Key Details

• Transaction date: 2026-09-10; filing date: 2026-09-11 (appears timely).
• Reported amount: 2,190 shares disposed for a total reported value of $4,380.
• Price details: reported weighted average price $2.00; block trade prices ranged $2.00–$2.03 (per footnote).
• Reason/footnote: Sale was a mandatory "sell-to-cover" to satisfy tax withholding on RSU vesting (footnote F1) — not a discretionary sale by the insider.

Context

• Sell-to-cover transactions are common when RSUs vest and generally reflect tax mechanics rather than a signal about the insider’s view of the company. This filing documents a routine tax-withholding sale rather than an opportunistic open-market disposal.
