BeOne Medicines (ONC) officer reports RSU grant and ADS tax-withholding sale

Rhea-AI Filing Summary

BeOne Medicines Ltd. principal accounting officer Titus B. Ball reported a mix of compensation-related share activity and tax-driven sales. On June 11, 2026, he had 169 American Depositary Shares sold in open-market transactions, with prices around $256–$258 per ADS.

These restricted share units vest in four equal annual installments starting on June 11, 2026, with potential accelerated vesting upon certain termination events. Each ADS represents 13 Ordinary Shares, connecting the ADS activity to the underlying ordinary share structure.

restricted share units financial

"Represents securities underlying restricted share units. 1/4th of the securities will vest on each anniversary of June 11, 2026, subject to continued service."

Restricted share units (RSUs) are a promise from a company to give an employee or service provider actual shares or cash equal to the shares after certain conditions are met, typically staying with the company for a set time or hitting performance targets. Think of them like a time-locked gift card that becomes usable only after you’ve earned it. For investors, RSUs matter because they align employee incentives with company performance and can increase the number of shares outstanding over time, diluting existing ownership and affecting earnings per share.

mandatory tax withholding financial

"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."

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.

accelerated vesting financial

"Unvested securities are subject to accelerated vesting upon certain termination events."
