Key Details

  • Transaction date: 2026-02-17
  • Transaction type/code: Sale (S); automatic sale to cover tax withholding on RSU vesting (Footnote F1)
  • Shares sold: 15,890; Weighted average price: $5.05; Total proceeds: ~$80,245
  • Reported price range: $5.04 to $5.24 across multiple trades (Footnote F2)
  • Shares owned after transaction: Not disclosed in this Form 4

Context
Withholding sales tied to RSU vesting are routine and used to cover tax obligations; they generally do not signal the insider’s view on the company’s prospects. Purchases are typically more informative about insider confidence. Footnote F2 states the filer can provide per-trade breakdowns on request if investors or the SEC need the exact number of shares sold at each price.
