4 terms

PNC Shares financial

"class “C” preferred shares (“PNC Shares”)"

mandatory redemption financial

"mandatory redemption of 15.46% of AXIA Energia S.A.’s outstanding PNC Shares"

Mandatory redemption is a contract clause that forces an issuer to buy back a security—such as a bond, preferred share, or convertible—under specified conditions or at scheduled times. For investors it matters because it determines when and how they will get their principal or liquidation value returned, affects the timing of income, and can change the total number of outstanding securities, similar to a store being required to repurchase a product on a set schedule.

RSUs financial

"the sum of (i) 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.
