American Depositary Share financial

"Each American Depositary Share represents 13 Ordinary Shares."

An American Depositary Share (ADS) is a U.S.-listed certificate that represents a specified number of shares in a foreign company, held by a custodian bank; it works like a receipt that allows U.S. investors to buy and trade foreign equity on American exchanges without dealing with another country’s markets. Investors care because ADSs make foreign stocks easier to access, improve liquidity and settlement in dollars, and can affect dividend payments, voting rights and regulatory oversight compared with buying the underlying foreign shares directly.

restricted share unit financial

"in connection with the vesting of a restricted share unit award previously granted"

A restricted share unit (RSU) is a promise by a company to give an employee a set number of company shares at a future date, typically after meeting time or performance conditions. For investors, RSUs matter because when they convert into actual shares they increase the number of shares outstanding (like unlocking more tickets in a game), which can dilute existing holders, and they align employee incentives with company performance, influencing behavior and long-term value.

FAQ

What insider transaction did BeOne Medicines (ONC) report in this Form 4?

BeOne Medicines reported that SVP and General Counsel Lee Chan Henry sold 1,044 American Depositary Shares on July 30, 2026 at $323.69 per ADS. The transaction was linked to tax withholding on a vesting restricted share unit award, not a discretionary open-market sale.

Why did Lee Chan Henry sell BeOne Medicines (ONC) ADS in this filing?

The 1,044 ADS sale was executed under a mandatory tax withholding provision in his restricted share unit award agreement. Shares were sold to satisfy tax obligations arising from RSU vesting, rather than as a voluntary portfolio reallocation or discretionary share sale.

How many BeOne Medicines (ONC) shares does Lee Chan Henry hold after the reported sale?

What is the conversion ratio between BeOne Medicines (ONC) ADS and Ordinary Shares?

Each BeOne Medicines American Depositary Share (ADS) represents 13 Ordinary Shares. This means the reported sale of 1,044 ADS corresponds economically to a multiple of the company’s ordinary shares, although the Form 4 itself expresses the transaction solely in ADS terms.

The Form 4 indicates the Rule 10b5-1 checkbox is not marked as an affirmatively adopted plan. Instead, the filing specifies the sale occurred under a mandatory tax withholding provision associated with a restricted share unit award, rather than a discretionary preset trading program.

How is the BeOne Medicines (ONC) restricted share unit award structured for this insider?
