Director Stock Option financial

"reported that director Brian Daniels received a grant of a Director Stock Option"

exercise price financial

"The options have an exercise price of $10.88 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.

vesting financial

"These options will vest in full on the earlier of September 8, 2027"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

annual stockholder meeting financial

"the date of Artiva’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.
