5 terms

Stock Option financial

"security_title: "Stock Option""

A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.

exercise price financial

"The exercise price is equal to the closing price of the Issuer's common stock"

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.

Nasdaq Capital Market financial

"closing price of the Issuer's common stock on the Nasdaq Capital Market on the date of grant"

The Nasdaq Capital Market is a platform where smaller, emerging companies can list their shares for trading by investors. It provides these companies with access to funding and visibility, helping them grow, much like a local marketplace where new vendors can introduce their products to potential customers. For investors, it offers opportunities to discover early-stage companies with growth potential.

vests in three equal annual installments financial

"The stock option vests in three equal annual installments with the first tranche vesting"

Common Shares financial

"underlying_security_title: "Common Shares""

Common shares are the basic units of ownership in a company that give holders a claim on profits and a right to vote on key matters, like electing the board. Think of them as membership cards in a club: they let you share in successes and losses, but in a bankruptcy or liquidation they are paid after creditors and preferred shareholders, so their value can swing more and matters for assessing risk and potential return.
