Restricted Stock Units financial

"Reflects cash-settled RSUs. Each RSU represents a contingent right to receive an amount in cash equal to the fair market value of one share"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

cash-settled RSUs financial

"Reflects cash-settled RSUs. Each RSU represents a contingent right to receive an amount in cash"

fair market value financial

"receive an amount in cash equal to the fair market value of one share of the Issuer's common stock"

The price a willing buyer and a willing seller would agree on for an asset or security when neither is under pressure and both have access to the same information. Think of it as the market’s neutral estimate of what something is worth, like the price two neighbors would settle on for a car after comparing similar listings. Investors care because fair market value guides buying and selling decisions, tax reporting, portfolio valuation, and how accurately company assets are reflected in financial statements.

vesting date financial

"on the applicable vesting date. The RSUs shall vest on the 2027 annual shareholder meeting date"
