Key Details

• Transaction date and price: Aug 19, 2026 — 260 ADSs at $27.00 each.
• Reported value: $7,020 (gross proceeds).
• ADS-to-ordinary conversion: Each ADS represents 10 ordinary shares, so this equals 2,600 ordinary shares (filing reports in ADSs per footnote).
• Plan/authorization: The sale was effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on Dec 9, 2025 (pre-established plan).
• Filing: Form 4 was filed Aug 21, 2026, reporting the Aug 19 transaction.
• Post-transaction holdings: Not specified in the provided filing excerpt.

Context

• A 10b5-1 plan indicates the sale was pre-scheduled under an established trading plan, which is commonly used by insiders to transact while limiting timing concerns. This was an open-market sale (S) and represents a modest dollar amount, so it is typically viewed as routine insider selling rather than a material signal about company prospects.
