stock options financial

"director Brian Daniels received a grant of stock options for 16,250 shares"

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.

exercise price financial

"The options have an exercise price of $10.42 per share"

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

"with an exercise price of $10.42 per share and an expiration date of September 9, 2036"

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised.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.

annual stockholder meeting regulatory

"will vest in full on the earlier of September 10, 2027, or the date of Artiva Biotherapeutics, Inc.'s 2027 annual stockholder meeting"

An annual stockholder meeting is a yearly gathering where a company's owners (shareholders) receive updates on performance, vote on key issues like board members, executive pay and major corporate plans, and ask questions of management. Think of it as a company town hall where choices about oversight and direction are decided; outcomes can affect management accountability, corporate strategy and ultimately the value and risks of investors’ shares.
