Key Terms

Stock Option (Right to Buy) financial

exercise price financial

"conversion_or_exercise_price: "38.9600""

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

"shares subject to the option shall vest upon the earlier of June 30, 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 meeting financial

"one (1) day prior to the Issuer's next annual meeting occurring after the grant date"

A company's annual meeting is a yearly gathering where owners (shareholders) and the board review performance, ask questions, and vote on key matters like electing directors, approving auditor choices, and sometimes setting pay or dividend policies. For investors it matters because decisions made and votes cast can change who runs the company, influence strategy and payouts, and affect the value or direction of their investment—similar to a homeowners’ meeting where rules and leaders that shape your property’s value are decided.

Is Yang Taiyin’s Kodiak Sciences (KOD) Form 4 transaction a stock sale or purchase?
