Restricted Stock Units financial
"Each RSU was granted on April 1, 2023, under the 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.
performance stock unit financial
"Each performance stock unit ("PSU") was granted on April 1, 2023"
A performance stock unit is a type of reward companies give to employees, usually managers, that depends on how well the company performs over time. If the company hits specific goals, the employee earns shares of stock, like earning a prize for reaching certain levels in a game. It motivates employees to work hard because their rewards are tied to the company's success.
2020 Incentive Plan financial
"under the Certara, Inc. ("Certara") 2020 Incentive Plan"
Rule 16b-3 regulatory
"withheld to satisfy tax withholding obligations ... exempt under Rule 16b-3"
Rule 16b-3 is a Securities and Exchange Commission regulation that exempts certain routine, pre-approved transactions by company insiders from automatic liability for short-term trading profits. It acts like a safe harbor: if an insider follows a formal plan or the board approves specific transactions in advance, profits from buying and selling company stock within six months are not automatically reclaimed. Investors care because the rule clarifies when insider trades are permissible and reduces uncertainty about potential clawbacks.
