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.

2021 Equity Incentive Plan financial

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

exercise price financial

"conversion_or_exercise_price": "1.4000""

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.

expiration date financial

"expiration_date": "2036-03-31T00:00:00.000Z""

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised. It matters to investors because it determines the timeframe during which they can take action or benefit from the contract, similar to how a coupon or a food item has a limited period of usefulness. Once the expiration date passes, the contract loses its value or ability to be used.
