Key Details

  • Transaction date: 2026-03-05 (filed 2026-03-06).
  • Exercise (code M): 36,920 shares acquired at $13.00/share — cost $479,960.
  • Sale (code S): 36,920 shares sold at $47.34/share — proceeds $1,747,922.
  • Filing also reports a derivative disposition of 36,920 shares at $0.00 (the form does not specify the reason).
  • Shares owned after the transaction: not disclosed in this Form 4.
  • Footnotes: the option was originally reported 1/3/2019 and was adjusted for 2-for-1 stock splits on 5/22/2019 and 5/21/2025; the option vests over five years (40% after two years, then 20% per year).

Context This was an option exercise followed by an immediate sale of the same shares (commonly seen when insiders exercise vested options and sell shares to realize gains). The filing appears timely (reported the day after the transaction). As always, sales by insiders can be routine (liquidity or tax-related) and do not by themselves indicate a change in company outlook.
