restricted share unit financial

"received a restricted share unit grant of 16,568 units under the AC Immune SA 2016 Stock Option and Incentive Plan"

A restricted share unit (RSU) is a promise by a company to give an employee a set number of company shares at a future date, typically after meeting time or performance conditions. For investors, RSUs matter because when they convert into actual shares they increase the number of shares outstanding (like unlocking more tickets in a game), which can dilute existing holders, and they align employee incentives with company performance, influencing behavior and long-term value.

Stock Option and Incentive Plan financial

"under the AC Immune SA 2016 Stock Option and Incentive Plan (SOIP)"

share options financial

"received share options with respect to 38,889 shares under the SOIP"

Share options are contracts that give someone the right, but not the obligation, to buy a company’s stock at a predetermined price for a limited time—think of them like a coupon to purchase shares later at a set price. They matter to investors because when exercised they increase the number of outstanding shares (dilution), can change management incentives and company value, and represent a potential future claim on profits or equity.

exercise price financial

"share options with respect to 38,889 shares under the SOIP ... exercise price of $2.62 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.

vest financial

"The share options will fully vest on June 10, 2027"

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.
