Deferred Stock Units financial

"1,737 deferred stock units ("DSUs") that vested"

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.

Equity Growth Program financial

"Under the terms of the IDT Corporation Equity Growth Program"

vesting date financial

"prior to the October 15, 2026 vesting date"

par value financial

"Class B Common Stock, par value $.01 per share"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.
