Insights

Routine RSU tax-withholding sale with substantial equity stake retained.

The filing shows Wang Lai disposed of 1,367 American Depositary Shares of BeOne Medicines Ltd. through open-market sales coded "S". Footnote detail explains this was mandated by a tax withholding provision tied to vesting of a restricted share unit award.

Such tax-driven sales are generally mechanical and carry weaker information content than discretionary selling. After the transactions, Wang Lai continues to hold 1,601,288 ordinary shares directly, plus indirect economic interests via Wang Holdings LLC and an RMB share employee plan, where he disclaims full beneficial ownership.

The employee plan acquired 2,069,546 RMB Shares at RMB192.6 per share in the STAR Market offering, and Wang Lai contributed RMB10 million. Future filings may clarify how additional RSU vesting and related tax withholding affect his reported holdings over subsequent anniversaries of the June 5, 2024 grant date.

  1. These securities are held by Wang Holdings LLC, the limited liability company interests of which are owned by the Reporting Person, his spouse and a trust created by the Reporting Person for the benefit of his spouse and children, for which the Reporting Person disclaims beneficial ownership. The term "RMB Shares" is used herein to represent the ordinary shares, par value $0.0001 per share, of the Issuer, issued directly by the Issuer in the Issuer's initial public offering on the Science and Technology Innovation Board (the "STAR Market") of the Shanghai Stock Exchange (the "STAR Offering"), to permitted investors in Renminbi ("RMB") within the People's Republic of China ("PRC") in accordance with the rules of the STAR Market. The Issuer established an employee participation program ("RMB Shares Employee Participation Plan"), which allows certain executive officers and qualified employees of the Issuer's subsidiaries in the PRC to indirectly participate in the STAR Offering and purchase certain RMB Shares from the Issuer through an asset management plan administrated by China International Capital Corporation Limited in a transaction that is exempt under Rule 16b-3. The RMB Share Employee Participation Plan purchased an aggregate of 2,069,546 RMB Shares directly from the Issuer in the STAR Offering at the initial public offering price of RMB192.6 per RMB Share (or $30.1295 based on an assumed exchange rate of $1.00 = RMB6.3924). The Reporting Person, as an individual participant in the RMB Shares Employee Participation Plan, has contributed RMB10 million to the RMB Shares Employee Participation Plan. The Reporting Person may be deemed to have indirect economic interest in an indeterminable portion of the RMB Shares held by the RMB Shares Employee Participation Plan but does not have voting or dispositive power over any of such shares. The Reporting Person disclaims Section 16 beneficial ownership of the RMB Shares held by the RMB Shares Employee Participation Plan, except to the extent, if any, of his pecuniary interest therein. This report shall not be deemed an admission that the Reporting Person is the beneficial owner of such RMB Shares for Section 16 or any other purpose. Each American Depositary Share represents 13 Ordinary Shares. The sale was effected pursuant to a mandatory tax withholding provision in the Reporting Person's restricted share unit award agreement in connection with the vesting of a restricted share unit award previously granted to the Reporting Person. 1/4th of the securities will vest on each anniversary of June 5, 2024, subject to continued service. Unvested securities are subject to accelerated vesting upon certain termination events following a change in control. The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $268.88 to $269.80, inclusive. The Reporting Person has provided to the Issuer, and undertakes to provide to the staff of the Securities and Exchange Commission or any security holder of the Issuer, upon request, full information regarding the number of American Depositary Shares sold at each separate price.

American Depositary Shares financial
"Each American Depositary Share represents 13 Ordinary Shares."
American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.

A Star Market is a specialized segment of a stock exchange designed to list fast-growing, technology- or innovation-focused companies under rules intended to make it easier for startups and research-driven firms to raise capital. For investors it matters because it provides a way to access potentially high-growth opportunities that come with higher risk and volatility—like buying early-stage products at a startup fair rather than established brands at a supermarket.
