5 terms

Restricted Stock Units ("RSUs") financial

"These shares were granted in the form of Restricted Stock Units ("RSUs"), in connection with the cash dividend"

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.

cash dividend financial

"in connection with the cash dividend paid on March 27, 2026, to stockholders of record as of March 13, 2026"

A cash dividend is a payment made by a company to its shareholders directly in money, usually on a regular schedule. It is a way for investors to receive a portion of the company's profits, similar to earning interest or a bonus for holding the company's stock. Cash dividends provide income to shareholders and can indicate the company's financial health and stability.

stockholders of record financial

"cash dividend paid on March 27, 2026, to stockholders of record as of March 13, 2026"

Stockholders of record are the people or entities whose names appear on a company's official shareholder list on a specific cutoff date set by the company or its transfer agent; only those listed are entitled to receive dividends, vote at shareholder meetings, or participate in other corporate actions. Think of it like a guest list for an event: being on the list on the set day determines who gets the benefits and rights, so investors must own shares before the cutoff to qualify.

unvested RSUs financial

"with respect to 1,160 unvested RSUs granted to the reporting person on August 12, 2022"
