Rule 144 regulatory

"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.

RSUs technical

"RSUs and PSUs"

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.

PSUs technical

"RSUs and PSUs"

PSUs are company shares promised to employees or executives that only become actual stock if the business hits specific performance targets over a set period. For investors, PSUs matter because they link pay to measurable outcomes — similar to a conditional bonus that converts into ownership — which can influence management decisions, dilution of shares, and signals about confidence in future results.
