restricted stock units financial

"Represents restricted stock units that will vest upon the earlier of (i) the 2027 annual meeting of stockholders..."

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.

annual meeting of stockholders financial

"will vest upon the earlier of (i) the 2027 annual meeting of stockholders of Celcuity Inc. or (ii) April 30, 2027."

beneficially own financial

"The reporting person continues to beneficially own these securities held by the trust."

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

trustees and beneficiaries financial

"The reporting person and his spouse are the trustees and beneficiaries."

Grant, award, or other acquisition financial
