• Shares owned after the transaction: not specified in the filing.
• Footnotes:
  • F1 — The 187,688 RSUs each convert to one share on vesting; they vest in equal annual installments over four years, with the first installment vesting March 1, 2027, subject to continued service.
  • F2 — The derivative/option award vests 25% after one year, with the remaining 75% vesting in 36 equal monthly installments thereafter, subject to continued service.
• No sales or exercises occurred in this filing; these are grants/compensation awards, not market purchases or dispositions.

Context
RSUs and time‑vesting options are standard executive compensation and do not involve immediate cash proceeds or share sales. These grants give the CEO the right to receive or exercise into shares over future vesting dates, subject to service conditions — they are not an immediate bullish purchase signal.
