Restricted Stock Unit financial

"Restricted Stock Unit Grant | Issuer | 844 | 05/18/2026 | Vesting"

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.

Rule 144 regulatory

"Securities To Be Sold | Restricted Stock Unit Grant | Vesting of Restricted Stock Units"

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.
