Restricted Shares financial

"The Restricted Shares will vest, without performance criteria, at the end of a one-year vesting period"

Restricted shares are company stock that cannot be sold or transferred immediately because they are subject to legal or contractual limits, such as a required holding period or performance conditions. They matter to investors because these locked-up shares can affect a company’s available stock for trading, future dilution, and insider incentives—imagine a gift that can’t be cashed until certain conditions are met, which changes when and how much supply can suddenly enter the market.

vesting period financial

"The Restricted Shares will vest, without performance criteria, at the end of a one-year vesting period"

A vesting period is the set amount of time someone must wait before they fully own granted shares, stock options, or other equity tied to their work or an agreement; ownership increases gradually or in steps during that time. Investors care because vesting determines when insiders or employees can sell shares, which affects future supply of stock, company incentives and executive retention—think of it like unlocking ownership over installments rather than receiving it all at once.

deferral election financial

"Such shares remain subject to a deferral election by the Reporting Person"

Treasury Regulation 1.409A-2 financial

"in accordance with Treasury Regulation 1.409A-2, and the vested portion thereof will be distributed"

separation of service financial

"will be distributed as shares of common stock following the Reporting Person's separation of service from the Board"
