Restricted Stock Unit financial
"security_title: "Restricted Stock Unit" with 100,000 underlying common shares"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
NQSO financial
"security_title: "NQSO" with 250,000 underlying shares at a $1.25 exercise price"
ISO financial
"security_title: "ISO" incentive stock options with a $1.67 exercise price"
An ISO is an incentive stock option, a form of employee benefit that lets workers buy company shares at a set price after a waiting period. It matters to investors because issuing ISOs can dilute existing shares and aligns employee incentives with long-term stock performance—think of it like giving employees coupons to buy future stock at today’s price, which can motivate growth but increase share count when used.
weighted average price financial
"footnote states the price reported is a weighted average price for multiple trades"
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
