• Transaction date: 2026-07-22; Form 4 filed: 2026-07-23 (timely).
• Exercise/Acquired: 225,000 shares at $8.90 each (paid $2,002,500).
• Sale/Disposed: 104,934 shares at an average price of $74.33 each (proceeds ~$7,799,776). Footnote F1 notes the sale price is an average; the filer can provide a per‑trade breakdown on request.

Context

• The same‑day exercise and sale pattern is consistent with a cashless or partial cashless exercise (exercising options and selling some shares to cover costs/taxes or to monetize gains). The filing shows both an acquisition via exercise and a separate open‑market sale on the same date.
• Sales by insiders can be routine (e.g., option exercises, tax withholding, diversification) and do not, by themselves, indicate the insider's view of the company. The $0 disposal of 225,000 derivative shares may reflect settlement/withholding treatment reported on the Form 4.
