Armour Residential REIT director Carolyn Downey received a grant of 17,140 phantom stock units. These units were awarded at no cash cost under Armour’s Fourth Amended and Restated 2009 Stock Incentive Plan and increase her phantom stock holdings to 32,154 units.

The phantom stock vests over a five-year, time-based schedule. Beginning on May 20, 2026, 857 units vest on each May 20, August 20, November 20, and February 20 through February 20, 2031, when all 17,140 units are scheduled to be fully vested.

Phantom Stock financial

"The reporting person was granted an aggregate of 17,140 phantom shares under ARMOUR Residential REIT, Inc.'s Fourth Amended and Restated 2009 Stock Incentive Plan"

A phantom stock is a form of compensation that gives employees or executives the benefits of stock ownership, such as the increase in stock value, without actually giving them real shares. It acts like a promise to pay the employee the equivalent value of company stock later, often as a bonus or incentive. This allows companies to motivate and reward staff without diluting ownership or transferring actual shares.

time-based vesting financial

"phantom shares under ARMOUR Residential REIT, Inc.'s Fourth Amended and Restated 2009 Stock Incentive Plan pursuant to the time-based vesting schedule"

Time-based vesting is a schedule that gives employees or contractors ownership of granted stock or options gradually as they remain with a company, like unlocking rewards in a loyalty program the longer you stick around. For investors, it matters because it affects future share supply, management incentives and staff retention — all of which can influence company performance and dilution of existing shareholders.

change in control financial

"will fully and automatically vest upon the reporting person's death, disability, and in the event of a change in control of ARMOUR"

A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.

withholding taxes financial

"The reporting person also has the right to elect to have withholding taxes or a portion thereof satisfied by reducing the number of shares"

Withholding taxes are amounts a payer or government takes out of payments — such as wages, interest, or dividends — before the recipient gets the money, functioning like a cashier keeping part of a bill to pay taxes on your behalf. For investors this matters because it reduces the cash they actually receive, affects net returns and yield calculations, and may require additional paperwork or treaty claims to recover or offset the withheld amount against final tax bills.

dividend distributions financial

"the reporting person will receive a cash payment in an amount equal to the cash dividend distributions paid in the ordinary course"

economic equivalent financial

"Each unit of phantom stock is the economic equivalent of one share of ARMOUR common stock"
