Key Details

• Transaction date and price: 79 shares withheld on 2026-02-18 at $88.96 per share (total $7,028).
• Transaction code: F (payment of exercise price or tax liability — a disposal via tax withholding).
• Shares owned after transaction (corrected): 9,990 total beneficially owned; 1,314 of those are unvested restricted stock units.
• Filing timeline: Original Form 4 was filed Feb 19, 2026 and contained clerical/rounding errors; this amended Form 4 was filed Feb 23, 2026 to correct the withheld share amount and beneficial ownership totals (see footnotes F1 and F2).

Context

• Tax withholding (code F) is a routine disposition to cover tax obligations from equity awards or option exercises; it is not an open-market sale and does not necessarily indicate buying/selling sentiment.
• The amendment corrects reporting details (number of shares withheld and totals of beneficially owned/unvested securities), improving accuracy for investors tracking insider holdings.
