Key Terms

Restricted Stock Units ("RSUs"), reverse stock split, beneficially owned, fully vested and exercisable

4 terms

Restricted Stock Units ("RSUs") financial

"These Restricted Stock Units ("RSUs") were granted to the Reporting Person"

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.

reverse stock split financial

"as a result of a 1-for-10 reverse stock split effected by the Issuer"

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.

beneficially owned financial

"The number of shares beneficially owned by the Reporting Person has been adjusted"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

fully vested and exercisable financial

"These options are fully vested and exercisable."
