Deferred Stock Units financial

"granted in the form of Deferred Stock Units"

Deferred stock units are promises from a company to give an employee shares of stock at a future date, often after certain conditions are met or after leaving the company. They function like a form of delayed compensation, allowing employees to earn shares over time. For investors, they represent potential future ownership in the company, but do not provide immediate voting rights or dividends until the shares are actually received.

stockholders of record financial

"stockholders of record as of September 18, 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.
