Restricted Stock Unit financial

"Each restricted stock unit (RSU) represents a contingent right to receive one share of the Issuer's common stock."

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

Stock Option financial

"Stock Option (right to buy) exercisable for 22,000 underlying shares of Common Stock."

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.

vest financial

"The RSUs vested on May 18, 2026, which was one day prior to the Issuer's 2026 Annual Meeting of Stockholders."

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

exercise price financial

"Stock option grant with an exercise price of 4.5200 per share expiring on May 19, 2036."

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.

Annual Meeting of Stockholders financial

"The RSUs vested on May 18, 2026, one day prior to the Issuer's 2026 Annual Meeting of Stockholders."
