Sanders Corazon (Corsee) D. 4

What Happened
Corazon (Corsee) D. Sanders, a director of BeOne Medicines Ltd. (ONC), disposed of 212 American Depositary Shares (ADS) on May 22, 2026. The shares were sold at $309.59 each, generating proceeds of $65,633. The filing indicates the sale was made to satisfy a mandatory tax-withholding requirement tied to the vesting of restricted share units (RSUs).

Key Details

• Transaction date and price: 2026-05-22, 212 ADS sold at $309.59 per ADS (total $65,633).
• Shares owned after transaction: not specified in the Form 4 provided.
• Footnotes: F1 — each ADS represents 13 ordinary shares; F2 — sale effected pursuant to mandatory tax withholding under the Reporting Person’s RSU award agreement (vesting schedule and change-in-control/termination acceleration described).
• Filing timeliness: Form filed 2026-05-27; this appears to be within the two-business-day SEC filing window for Section 16 insiders (timely).

Context
The sale was done to cover tax withholding on vested RSUs (a common, routine reason for insider sales) rather than a separate discretionary open-market divestiture. Because each ADS equals 13 ordinary shares, the 212 ADS correspond to 2,756 underlying ordinary shares. The RSU footnote describes standard vesting and accelerated-vesting on certain events; the transaction should be read as tax-withholding related rather than a direct signal about the director’s view of the company.
