restricted shares financial

"Represents restricted shares of Common Stock that will time vest over three years"

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.

continued employment financial

"will time vest over three years subject to continued employment with the issuer"

Continued employment means that an individual remains in their current job without interruption. For investors, it signals stability and ongoing work that can affect company performance and future prospects. Like a steady heartbeat for a business, sustained employment helps ensure consistent operations and financial health.
