Stock Options financial

"The stock options, granted on March 31, 2026 pursuant to the MAIA Biotechnology, Inc's 2021 Equity Incentive Plan"

Stock options are agreements that give a person the right to buy or sell a company's stock at a specific price within a certain time frame. They are often used as a reward or incentive, similar to a coupon that can be used later if the stock price rises, allowing the holder to make a profit.

"representing the right to buy shares of common stock, vest 100% on the date of the grant"

exercise price financial

"conversion or exercise price of $1.4000 per share for the stock options"

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
