Restricted Stock Units financial

"Each restricted stock unit ("RSU") was granted on May 21, 2025, under the Certara, Inc. 2020 Incentive Plan"

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.

It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth.
