Key Details

• Transaction date: August 11, 2026; Form 4 filed August 13, 2026 (timely — within required reporting window).
• Open-market sale: 2,666 shares @ $360.00 = $959,760; sale effected under a Rule 10b5-1 plan (Footnote F2).
• Option exercises (acquired): 812 @ $194.47 ($157,910); 1,058 @ $213.32 ($225,693); 796 @ $159.03 ($126,588). Total exercised-acquired shares = 2,666.
• Derivative dispositions (reported at $0): 10,556; 13,754; 10,348 shares — shown as disposals of derivative securities in the filing.
• Footnotes of note: F1 — each American Depositary Share (ADS) represents 13 ordinary shares; F3 — option counts/prices are represented in ordinary shares; F4–F6 — vesting schedules for related awards (multi-year vesting with acceleration on certain terminations).
• Shares owned after the transactions: not specified in the information provided.

Context

• This is an option exercise combined with an immediate sale of the shares acquired (the numbers acquired equal the shares sold). The filing also shows zero-dollar derivative dispositions — commonly used to indicate shares were surrendered/used in relation to exercises or tax withholding; the filing records these as dispositions but does not explain the mechanics.
• The sale was executed under a pre-established Rule 10b5-1 trading plan (per F2), which is a common method executives use to schedule sales and reduces the implication of opportunistic timing.
• This report is transactional and factual; it does not state the insider’s motivations.
