Key Details
- Transaction date: Feb 4, 2026; Form 4 filed Feb 6, 2026 (filed within the typical 2-business-day window).
- Conversion: 12,133 RSUs converted into shares (no exercise price).
- Withholding/sale: 4,775 shares sold/withheld at $297.45 each for $1,420,324 to cover taxes.
- Net shares received by insider: 7,358 shares.
- Footnotes: F1 = shares withheld to satisfy tax withholding; F2 = each RSU equals one share or cash equivalent; F3 = these RSUs were part of a 36,400 RSU grant on Feb 4, 2025 that vests ratably over a three-year schedule.
- Shares owned after transaction: not disclosed in the provided filing.
Context
- This was a conversion/vesting event of RSUs with a routine tax-withholding sale — common for equity-compensation settlements and not necessarily a sign of confidence or concern by the insider. Because the RSUs had no exercise price, the conversion is recorded as a derivative conversion (M) and the withholding is recorded separately (F).
- Purchases tend to be a stronger bullish signal for investors; tax-related withholdings are administrative.
