restricted stock units ("RSUs") financial

"the reporting person was granted 47,619 restricted stock units ("RSUs"), each representing the 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.

Common Stock financial

"each representing the right to receive one share of common stock of MultiSensor AI Holdings, Inc."

It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
