Restricted Stock Unit financial

"security_title: "Restricted Stock Unit""

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

RSUs financial

"represents a grant ... of 21,154 restricted stock units ("RSUs")."

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.

Board of Directors financial

"Represents a grant, on June 22, 2026, by the issuer's Board of Directors"
