Restricted Stock Units financial

"Reflects shares of common stock delivered upon vesting and settlement of previously awarded restricted stock units ("RSUs")."

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.

RSUs financial

"On February 28, 2024, the reporting person was granted 56,603 RSUs, vesting in three substantially equal annual installments."

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

contingent right financial

"Each RSU represents a contingent right to receive either one share of Common Stock or an amount of cash equal to the fair market value."

fair market value financial

"An amount of cash equal to the fair market value of one share of 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.

taxes payable financial

"Reflects shares of Common Stock withheld to satisfy taxes payable in connection with the vesting and settlement of previously awarded RSUs."
