Restricted Stock Units financial

"The restricted stock units (RSUs) convert into common stock of Tutor Perini Corporation"

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.

RSUs financial

"On May 20, 2026, the reporting person was granted 10,971 RSUs, of which 3,657 vest"

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

1-for-1 basis financial

"The restricted stock units (RSUs) convert into common stock of Tutor Perini Corporation on a 1-for-1 basis."

vesting financial

"3,657 vest on each of May 20, 2027, 2028 and 2029, contingent upon continued employment"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.

continued employment financial

"vest on each of May 20, 2027, 2028 and 2029, contingent upon the reporting person's continued employment"

Continued employment means that an individual remains in their current job without interruption. For investors, it signals stability and ongoing work that can affect company performance and future prospects. Like a steady heartbeat for a business, sustained employment helps ensure consistent operations and financial health.
