Incentive Stock Option financial
"security_title: "Incentive Stock Option (right to buy)""
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.
