Key Details

• Transaction date: July 1, 2026; Filing date (Form 4): July 6, 2026 — this is five days after the trade and outside the typical two-business‑day Form 4 window, so the filing appears late.
• Price: Weighted average $124.91; individual sale prices ranged $124.900–$124.940 per share (holder can provide per‑price breakdown on request).
• Shares disposed: 801 shares; total proceeds ≈ $100,056.
• Shares owned after transaction: Not specified in the information provided on this filing.
• Notable footnote: Transaction was effected under a Rule 10b5‑1 trading plan adopted March 6, 2026 (pre‑arranged trading plan).

Context

• Because the sale was executed under a 10b5‑1 plan, it was likely pre‑scheduled and may not reflect the insider’s current view of the company. Sales are common for insiders for liquidity or diversification; purchases generally carry more weight when assessing insider sentiment.
