Restricted Share Units financial

"Represents Common Shares earned and vested under a restricted share unit ("RSU") award"

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.

net settlement financial

"withheld by the issuer to satisfy income tax withholding and remittance obligations in connection with the net settlement of the RSUs"

Share Option (Right to Buy) financial

"security_title": "Share Option (Right to Buy)""

income tax withholding financial

"withheld by the issuer to satisfy income tax withholding and remittance obligations"

annual meeting of shareholders financial

"the day before the date of the issuer's 2027 annual meeting of shareholders"

A yearly gathering where a company’s owners (shareholders) vote on key items like electing the board, approving executive pay, and ratifying auditors, and receive updates on performance and strategy. Think of it as an annual town hall for owners: it matters to investors because outcomes and disclosures can affect leadership, corporate direction, dividend and governance policies, and therefore the company’s risk and potential return.
