  • Price used: $43.63 per share (footnote: Nasdaq close on the last preceding business day, March 13, 2026)

Context

  • This type of disposal is typically a routine tax-withholding action tied to option exercises or restricted share vesting (shares are surrendered to cover taxes). It is not the same as an open-market sale and does not necessarily signal a change in the insider’s view of the company. Purchases are generally more informative about insider sentiment.
