restricted stock units financial

"the reporting person was granted 1,869 restricted stock units ("RSUs"), each representing the right to receive one share"

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.

2023 Incentive Award Plan financial

"common stock of MultiSensor AI Holdings, Inc. (the "Issuer") pursuant to the Issuer's 2023 Incentive Award Plan"

reverse stock split financial

"retroactively adjusted to reflect the Issuer's reverse stock split of its outstanding shares of common stock"

A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.
