4 terms

Stock Option (Right to Buy) financial

"security_title: Stock Option (Right to Buy)"

exercise price financial

"conversion_or_exercise_price: 1.7900"

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: 2036-06-17T00:00:00.000Z"

The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised.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

Annual Meeting financial

"earlier of the first anniversary of the date of grant or (ii) the date of the next Annual Meeting"

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.
