restricted stock financial

"Represents restricted stock granted to the reporting person under the Issuer's 2018 Equity Plan"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

2018 Equity Plan financial

"granted to the reporting person under the Issuer's 2018 Equity Plan"

vesting schedule financial

"with the following grant and vesting schedule: 200,000 (awarded November 6, 2023)..."

A vesting schedule is a timeline that determines when someone gains full ownership of certain benefits, such as company stock or retirement contributions. Think of it like earning the right to own a gift gradually over time, rather than receiving it all at once. It matters to investors because it affects when they can fully access or sell these benefits, influencing their financial planning and decision-making.

forfeiture financial

"Such restricted stock are subject to forfeiture if the requisite service period is not completed."
