Restricted Stock Units financial

"Represents conversion of 30 restricted stock units ("RSUs") granted to the reporting"

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.

reverse stock split financial

"as adjusted for 1-for-35 reverse stock split of the Issuer's 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.

contingent right financial

"Each restricted stock unit represents a contingent right to receive one share"

tax liability financial

"These shares were sold to pay tax liability associated with the vesting of RSUs"
