2021 Equity Incentive Plan financial

"granted on June 30, 2026 pursuant to the MAIA Biotechnology, Inc's 2021 Equity Incentive Plan"

Stock Options financial

"The stock options, granted on June 30, 2026 pursuant to the MAIA Biotechnology"

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.

Common Stock financial

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

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.

beneficially owned financial

"These securities are beneficially owned by Mr. Smith through The Stan V. Smith Trust"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

Trust financial

"beneficially owned by Mr. Smith through The Stan V. Smith Trust Dated 1993"

A trust is a legal setup in which one party (the trustee) holds and manages assets—like cash, stocks or property—on behalf of other people (beneficiaries) according to instructions from the person who created it (the grantor). Think of it as a locked box with a keyholder who must follow written rules; for investors it matters because trusts influence who controls and benefits from assets, affect taxes and succession, and can change how quickly or transparently shares are bought, sold or voted.
