• 1,546 shares at $447.18 — $691,345

These transactions are sales (not purchases), which are often routine liquidity events for insiders rather than direct signals about company fundamentals.

Key Details

• Transaction date: August 11, 2026 (reported on Form 4 filed Aug 12, 2026).
• Aggregate shares sold: 20,000; aggregate proceeds: ~$8.90 million.
• Per-tranche weighted average prices and ranges are documented in the filing (see footnotes): each tranche has a weighted average price and reported intra-tranche price ranges.
• Footnote F1: Sales were effected pursuant to a Rule 10b5-1 trading plan adopted by Mr. Irving on Feb 5, 2026.
• Footnotes F2–F8: Each sale line represents a weighted average sale price for multiple transactions, with disclosed low/high price ranges for each tranche; the filer will provide detailed per-price breakdowns on request.
• Shares owned after transaction: Not specified in the provided excerpt of the filing.
• Timeliness: Filing appears timely (transaction 8/11/2026; Form 4 filed 8/12/2026).

Context

• 10b5-1 trading plans are pre-established schedules that allow insiders to sell shares at pre-set times or under set conditions; trades under such plans are generally considered routine and reduce the likelihood that the insider was trading on undisclosed material information.
• For retail investors, purchases by insiders can be more informative about confidence than scheduled sales; these sales alone do not provide evidence about the company’s near-term prospects.
• If you want the exact per-lot price breakdowns (beyond the weighted averages and ranges), the filer states they will provide that detail to the issuer, any shareholder, or the SEC staff upon request.
