phantom stock financial

"Represents additional shares of phantom stock/RSUs credited to the reporting person's account under the Amended and Restated GATX Directors' Phantom Stock 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.

RSUs financial

"Each share of phantom stock/RSU represents the right to receive one share of Issuer's common stock upon settlement"

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

dividend reinvestment feature financial

"Represents 124 shares of phantom stock/RSUs acquired pursuant to the dividend reinvestment feature of the Phantom Stock Plan and the Deferred Fee Plan"

Deferred Fee Plan financial

"the Amended and Restated GATX Corporation Directors' Voluntary Deferred Fee Plan ("Deferred Fee Plan") credited on the transaction date"
