Deferred Stock Units financial

"Represents quarterly director equity retainer paid under the Southern Company 2021 Equity and Incentive Compensation Plan and deferred pursuant to the Deferred Compensation Plan"

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.
