Restricted Stock Award financial

"Restricted Stock Award pursuant to 2022 Stock Incentive Plan. Vests 25% per year."

A restricted stock award is company shares given to an employee or executive that cannot be sold or fully owned until certain conditions—like staying with the company for a set time or hitting performance targets—are met. Think of it as a gift that only becomes yours after you fulfill specific obligations; for investors, these awards matter because they can increase the total shares outstanding when they vest, reveal how management is being paid and motivated, and create potential selling pressure when restrictions lift.

Incentive Stock Option financial

"Incentive Stock Option pursuant to 2022 Stock Incentive Plan."

An incentive stock option is a type of employee benefit that gives a worker the right to buy company shares at a fixed price, with special tax advantages if the employee holds the shares for a required period. Think of it as a coupon to buy future shares at today’s price that can result in lower tax on the gain. Investors care because ISOs can dilute share count, align staff incentives with the stock price, and affect company compensation costs and the timing of potential share sales.
