Restricted Stock Units financial

"Each restricted stock unit ("RSU") was granted on February 27, 2026, 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.

2020 Incentive Plan financial

"under the Certara, Inc. 2020 Incentive Plan ("2020 Incentive Plan") entitling the reporting person to receive one share"

annual meeting financial

"The RSUs vested and were converted to common stock on May 14, 2026, the day of the issuer's annual meeting"

A company's annual meeting is a yearly gathering where owners (shareholders) and the board review performance, ask questions, and vote on key matters like electing directors, approving auditor choices, and sometimes setting pay or dividend policies. For investors it matters because decisions made and votes cast can change who runs the company, influence strategy and payouts, and affect the value or direction of their investment—similar to a homeowners’ meeting where rules and leaders that shape your property’s value are decided.
