Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

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.

Restricted Share Units financial

"Restricted Share Units Vested Under an Issuer S-8 Registered Plan"

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.

S-8 Registered Plan regulatory

"Restricted Share Units Vested Under an Issuer S-8 Registered Plan"

sell-to-cover arrangement financial

"pursuant to a mandatory, non-discretionary, sell-to-cover arrangement"

performance share unit awards financial

"upon vesting of performance share unit awards only."
