Key Terms

4 terms

restricted stock units ("RSUs") financial

"Represents restricted stock units ("RSUs"), each one of which represents the contingent right to receive one share"

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

contingent right financial

"each one of which represents the contingent right to receive one share of the Issuer's common stock"

vest financial

"The RSUs will vest on the earlier of the one-year anniversary of the grant date"

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

annual meeting of the Issuer's stockholders financial

"the next annual meeting of the Issuer's stockholders following the grant date"

When do the RSUs reported for Lumexa Imaging (LMRI) vest?

The RSUs vest on the earlier of one year after the grant date or the next annual stockholder meeting. Vesting is conditioned on the director’s continued service with Lumexa Imaging, so leaving the board before that time could affect how many units ultimately vest.
