Restricted Stock Units financial

"Each restricted stock unit ("RSU") represents a contingent right to receive one share"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

tax withholding obligations financial

"represents shares sold by the Reporting Person to cover tax withholding obligations"

vest in three equal annual installments financial

"The RSUs vest in three equal annual installments beginning on April 15, 2026"

Employee Stock Option (right to buy) financial

"Employee Stock Option (right to buy)"

exercise price financial

"The stock option vests in three equal annual installments beginning on April 15, 2027"

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.
